Cab to engine compartment wire routing...

Ideas/suggestions on what you have done or where you have routed wiring from the driver/passenger area to the engine bay thur the firewall.

if I have to wire something on the drivers side, there was a hidden hole underneith the power brake booster on my truck, so everything goes through there.

If its on the passenger side, I have a somewhat large hole with a large rubber grommit in it. On the inside of the truck, it comes through under the ECM just about as high up as you can go w/o being a pain in the ass.

In order to get to it from the engine compartment, you have to remove the inner fender, but it helps keep everything hidden.

Your suggestion on removing the inner fender, is that for either side?

And thanks for your help.

:D

There's a couple of other ones. One is to the right (Pass.) side of the hump and U have to pull the rug to get at it. In the engine compartment it has a heat shield around it, but it's hard to get at w the Downpipe in. I drilled another hole there.

Ed says there is one behind the radio also. There's one high on the drivers side where the E-Brake cable goes thru. I drilled another one next to that one also. Most of my wires went thru the one above the brake pedal - it's a pretty big one.

I hadn't heard of the one near the ECM - good find !

be aware that the close proximity of this hole (its actually for the antennae) to the downpipe that wireing will be subject to heat and will deteriorate quickly, speaking from experiecne! kinda like the purple wire to the starter getting cooked.

An alternative is to make a hole on the pass side firewall viewed from the front behind the regulator to the right of the dashbord supporting stud. 1 inch to the right of the stud. with the radio out fishing thru isnt so bad.

thru this new hole i have run
1 new dfi injector wiring harness plug
2 wide band o2 wires
3 innovative msbc boost control solenoid wires
4 innovative map sensor wires
5 probably something else besides the above that i just cant remember (its an age thing ) :D

Very old thread I know.... but, ED is there any chance that you have a pic of this location from the engine bay? I think I understand it, but fear drilling before I am certain. I assume I'll be fishing the wires throug between the glove box and dash vent above the radio?

I'm running my WB wire throug and don't care to go from PA side near ECM to the DR side to go through and back to PA side to plug it into the DP. I also would prefer not to take the inner fender out.

Sounds like this is a great location, may even run other gauge wires through this spot.

Re: Cab to engine compartment wire routing...

I did my wiring through the hole (fresh vent) on the passenger side. No hole needs, remove the passereger inner fender you will see a gap vertically and you can feed it in that way it comes on into the fresh are vent in passenger compartment, (you need to have it open to fit the wiring through, but for me I already had it that way for the door speakers anyways. The nice thing bout that hole into the engine copmpartment is you can also easily feed it into the inner fender and have it comout my the blower motor to easiy reach the DP. The only other issue with the hole is that it more of a gap, so you can't put a grommet on it, so you need to properly sheld the wires from chaffing.
