How To Install Tekonsha Primus Brake Control


Primus Brake Control

Today on our 2016 chevrolet silverado 1500 we’re gonna take a look at and also

show you how to install the tekonsha primus IQ proportional trailer brake

controller this is going to work for one up to three axles its part number is

th9001pro for the electronic brake controllers part number three zero one

six now the button on top is gonna allow us to change what’s called the boost

mode this is going to be the quickness and aggressiveness in which our brakes

are applied when we have a smaller trailer and relation to our truck we’ll

probably have our boost mode here where it’s no boost at all as that trailer

size gets greater we can increase that all the way up to boost mode three and

that’s going to be the quickest and most aggressive application of our brakes

here on the side we’ve got our adjustable gain see we turn that all the

way down just registering zero and we can adjust that up by the tenth of a

digit the higher that number goes the more braking power is going to be sent

to the rear of the vehicle there so again our heavier trailers this is going

to need to be higher on smaller trailers we can adjust that lower the manual

override lever when applied is only going to go up to the preset game that

we have dialed in so we’ll never have to worry about even in a sway situation

where we need to apply the brakes we’re not going to overdo it and cause a

lock-up on the braking wheels on our trailer so that’s really nice now the

primus IQ is a really good brake controller as we said it’s gonna work

for up to three axles so that would be a six total brake assemblies designed as a

proportional system so it’s gonna break in proportion to your vehicle as we

apply the brakes in the truck the accelerometer or the the sensor inside

picks up on that and start sending braking power to the trailer the benefit

to that over a time-delayed system is that we don’t have to wait for that to

slowly ramp up this is going to give us the braking force that we need as soon

as we need it if we’re going into just the standard stop pulling up to a stop

light it’s gonna give us minimal braking force because it can sense that on the

other hand if it’s an emergency situation and really stand on the brakes

in the truck trying to get it halted it also senses that and it’s going to send

the maximum output that we’ve got dialed in back to the trailer helping to get

everything slowed down appropriately our manual will override lever you can see

here is easy to get to and we can use this to apply just a little bit of

braking force and as we go up its going to go all the way up to the maximum that

we have set with our gain dial a few other safeguards of the primus IQ are

gonna be short protection so the brake controller is going to protect itself

from any shorts or anything that we might get from our trailer also in the

event of a prolonged stop we pull up to a stop light we’ve been sitting there

for an extended period of time the primus IQ is slowly going to reduce the

amount of braking power that’s being sent to the brakes themselves to help

reduce any kind of overheating issues here’s what our primus IQ kits going to

look like we’re gonna have the brake controller itself got our bracket that

allows for easy removal and then we’ve got our more permanently fixed bracket

now that customer decided he wants to go that route which I do like these I like

the way they mount up and most of the time you’re not going to be removing and

putting your brake controller back in that’s going to be up to you it also has

a pigtail here that you can use to hardwire into your vehicle but on our

Silverado it’s been pre-wired for use with a brake controller so what we’re

going to use is part number three zero one six this is going to plug right into

our factory connection it’s going to give us all of the input and all of the

feeds that we need to get the information back through the blue wire

to our trailer to activate the brakes also it’s going to give us our ground

the stoplight signal and also our power DC is going to come with six self

tapping screws that’s all you need to get it installed we’re gonna be using a

bit driver quarter inch bit and then also I’ve got a small ratcheting quarter

inch drive you could use a quarter inch opening box wrench as well if there’s

any tight areas in there where you need to operate let’s head underneath the

dashboard now we’ll get it installed and to begin our installation we need to

find our factory port to plug in our pigtail

here just want to go to the right of the brake pedal slightly and there’s gonna

be a black box here on the backside on that there’s gonna be a couple of tabs

here it’s indicated where the locks are we’ve got two on this side

you’d be one on the other side just want to pull out on those tabs just you see

how that kind of opens up there this one on the inside can be a little tricky to

get to may have to use a flat blade screwdriver for it then we’ll just pull

that down and off and we’ll see our connection point our plug ins gonna be

located right here you see you’ve got large white plug Green plug the larger

opening here or you may have something plugged in there but it’ll be right

above it right there the white end is going to plug in we want the locking tab

to be facing the driver side of the vehicle we slide it into position and

you’ll just want to push that in until you hear it click and then you should be

able to pull out on that plug without it coming out be in good shape there now I

like to just guide my wire try to kind of right up like that and then when we

put that cover back on its gonna be exposed out of the top you see that

cover it’s not closed on the top so it’ll be a great area to get our wiring

out of that panel then we just give it cover line back up with those locking

tab marks I’m gonna just press in it’s gonna clip right on there we’re gonna be

mounting our controller right up here so that’s going to be kind of visible so

we’re gonna wrap this up a little bit with some electrical tape just to keep

it nice and neat looking all right I was just kind of mock-up our

controller here right where we want it looks like right there’s gonna be a good

spot when we position our bracket you can see there’s a oval-shaped hole you

have three round holes in one longer oval shape you’ll want that to be

towards the back and we’ll just use the self-tapping screws and just get it

secured just want to run these in there too they’re snug and you see it’s gonna

be a nice solid secure bracket see on the side of the controller here if

you’re using the metal bracket you’re going to use the two holes to secure it

if you’re using the plastic bracket it’s going to clip into one of those three

slides so just depending on your application that’s where those will go

in our case we’re gonna line the holes with the hole in the bracket now as we

get this secured we’ll want to do it in all four locations there and so we’ve

got that in we just need to plug in our pigtail so I’m gonna go right in the

back the tab it’s gonna go up like that in get an NC flashing there that’s gonna

indicate that we do have power coming to it so we won’t have to worry about any

additional connections or hookups to make this point we’re ready to plug in

our trailer see it operate and start enjoying our truck we’ll run a test on

it just to make sure it’s putting out power back to the 7-way plug which we

can show you now now you can see when we plug in our trailer in our case a

trailer tester it’s going to show that we do in fact have a trailer connected a

nice safeguard built in is that any event that does become disconnected

notice how that screen is going to change indicating NC kind of flashes at

you it’s going to let us know we need to go back and address the connection

between our truck and trailer now here you’ll see the test we’ll just use our

manual override lever you can see how that’s going to work is we give it more

and more pressure let’s go bring our both our voltage and our

current up higher and higher which we’ll be activating our brakes now you’ll see

here we do have just a little bit of excess pigtail so I’m going to do is

just draw that back see up here it’s plenty far out of the way he’s going to

zip tight right off to another wiring loom that’s up here with everything

working properly that completes our installation of the tekonsha primus IQ

part number tk90160 on our 2016 chevrolet silverado 1500.
