Ok guys I am getting ready to mount my ECM in the engine bay and was wondering what everyone else has done. Let's see some pics.

This is my 72 k20 it's mounted drivers side radiator support

Some folks rolled their eyes at me for exposing all of my wiring in the engine bay, but its easy to troubleshoot and the ecm has effective cooling there. Its been like this for a couple yeare but I'll be forced to move it when we take the inner fenders out.

I put mine inside the glove box along with all of my fuses and relays.

That's where I was thinking I would mount mine. I think it looks fine there plus like you said it's easy to access.
Thanks for the pic.

Great idea, thanks for posting pictures!

Did mine similar to TRKFRK. Made a bracket and mounted it behind the glove box so that the ECM would be at an angle. I trimmed the card board to hide the ECM but still be able to use it as a glove box. The only thing you can see when you open the glove box is the OBDII port

That's clean...

I put mine on the passenger side inner fender, I took the factory bracket and cut off the extra plastic and then put rubber feet on it and screwed it down. It works great and should not get to hot. I tried to find a good place in the cab but I did not want to lose the glove box and this just seemed a lot easier.

jadedbird · 04-25-2015, 06:12 PM

are you guys using stock truck harnesses? and are you modifying them at all? or are these stock length? and do you tie them into your existing truck harnesseS?

BR3W CITY · 04-25-2015, 06:36 PM

Mine is a custom made harness, but IMO the most versatile stock harness to start with is the service vans. Its got the longest main branches, and everything comes out in only a few places.

The trucks, cars and vans all have the same wiring types, just in different lenghts/branches.

Here is a nice mount that can be used in many different locations... $45

I put mine in the glove box also. I cut the backside of it out for the connections to come through and it fit nice and tight no movement at all.
I still have a little storage room but I use the center console for most stuff anyway!

josueh95 · 07-30-2015, 03:04 AM

i put mine under the bench seat, might or might not work with a stock harness, mine is an aftermarket made by current performance
