DGioMack Posted September 5, 2005 Share Posted September 5, 2005 Anyone able to help me ID these wires on the back of my truck cab.Also, I'm not an expert by any means with the workings of this truck or the electrical system, but it seems to me that this should not be just hanging here the way it is...

Superdog Posted September 5, 2005 Share Posted September 5, 2005 thats just the junction block for the trailer cord ,and tail,brake and turn signals for the back of the tractor.It's supposed to be attached at the bottom back left side of cab and there's a little cover plate that goes over it.

DGioMack Posted September 5, 2005 Author Share Posted September 5, 2005 oh ok, Thanks !!I think that will help me try to figure out my electrical issues, as far as eliminating what wire does what!Thanks for the help!! Is it imperative that its covered? I would imagine the elements cant be too good for those small wires.

Lmackattack Posted September 6, 2005 Share Posted September 6, 2005 I always wondered the same thing...why truck MFG let the wire ends live in the exposed weather conditions. even the R models have the main cab junction block on the fire wall ON THE OUTSIDE!!!!???However I am suprized how long they last! My B model had lots of spliced wires but the ends were fine. the only problem I found on the ends were when I tried to remove them from the studs..and the studs were correded or just would spinn in the jct block. They make a junction block with a rubber grommet and a cover with a rubber seal. I saw one on the internet for hot rodders and want to get a few for both the R and B model Quote Link to comment https://www.bigmacktrucks.com/topic/327-a-little-help/#findComment-1409 Share on other sites More sharing options...

I buy lots of stuff from Utility, air, elec, and load securement they are usually well stocked with just about anything you need and cost less than the truck dealers Doug Quote Link to comment https://www.bigmacktrucks.com/topic/327-a-little-help/#findComment-1412 Share on other sites More sharing options...

It does a hell of a job on keeping corrosion down.... walmart carries a brand of the tape, but it isnt as quality...... the terminals arent what you check; the corrosion usually is inside the wire next to the connectorjust dab some liquid tape on the connector and you'll rarely have a problem..
