PostSubject: Running The Sending Unit Lines    October 11th 2010, 10:45 am

I was trying to running the lines for my 3 gauge pod on my Silverado DMax. But I can never seem to find my fish wire/rod. Mad
I would use an existing wire and grommet, slide a 24" long screwdriver in along side the wire. Then from under the dash, look to see where it came in. I can never find it. Trust me, I tried everything. Blindly feeling for it. Stuck an LED trouble light in there. Still nothing.

I've come to the conclusion that Diesel trucks must have double fire walls.

Any suggestions would be very helpful. I'm thanken I have to either run my lines out through a hole in the A piller then into the engine compartment via the inner L fender. Or through the floor then back up the fire wall in the engine compartment. Mad

Sad thing about all this messing around. I can't afford to take the long way. My Pyro sending unit isn't that long. It can't be cut or spliced

i have run into that problem before.. it isnt so much a double firewall but your eyes are playing tricks on you.. something that looks like it should be in the middle of the inside firewall is accually under the rug.. lol.. i would drill a whole reletively close to the steering shaft comes though and go from there.. then you have a good idea where you are in the truck..

I'm serious and I'm very sure I'm not missing it. I sent a 2 ft long screwdriver into this grommet from the engine side and it was nowhere to be seen under the dash.

I think the next time my son can spare a few minutes I'll get him to be my spotter.
If he can HEAR or FEEL my screwdriver I might get further ahead with some help.

I'm a lil hesitant just drilling a hole without being sure I will find it on the other side.

Height also has a lot to do with it. If you drilled a hole in the floor board near the brake pedal, in the engine bay you'd be down near the frame rail. Just something to keep in mind.

What are you saying Rob? The fire wall IS dbl wall and the closer you get to the floor the closer the dbl wall is to each other.
Cause I noticed up by the wiper arms the dbl wall is like 12" thick. What I mean is there is a 12" gap in between the firewall and the engine compartment wall.

oh your sending it into your cowl... if you take off the plastic peices on the outside of the truck under the windsheild then you should be able to see where its going and then route it into the cab through there..

Let me look at mine and get back to you Glenn. I really dont know for sure. My other post was just an FYI that a lot of stuff on trucks has to do with angles.

You know what Joe. That does make cents. Do I ever feel like an idiot.
Hopefully it might get a bit warmer this weekend. I'll give it another try.

Glenn,
Have you tried running the wire from the inside of the cab through to the engine compartment? Got to be easier to spot where it comes through the firewall that way.

Hey John!!! Welcome to My Truck Source buddy.
Glad you could make it over from the Silverado and Sierra site.

Actually I considered that too, but I have found both sides of the fire wall are just as busy. (cluttered)

I found it was easier to visually select a already exiting grommet to send my fish wire through from the engine compartment. Then it was to visually find a grommet from under the dash.
Still a work in progress. getting cold up here now.

there should be a grommet near the steering-shaft, that you can fish your wires through, thats where my DSP5 wire when through, and it was easy-peasy to find, i just used a pen and taped the wire to it

I looked for one, I don't know, maybe the LBZ is a lil different then the LMM But I have very little in the line of useful grommets. The first one I tried, I think sent me right into the coul I think I'll just do the safe thing and take it through the floor then up the outside of the firewall.

LBZ and LMM are identical, my brother has an 07.5 and we sent the wire through the same spot, it comes out high up under the dash, but you can reach it, its kind of a PITA to do but you can do it
