Redoing wiring in engine compartment-what wire do I use?(Only trust diesel heads)
 

This is not really Diesel, but I only trust diesel heads.
I am redoing my Fuel Injection wiring on my Volvo 940 Turbo 1991 which may have failed due to the high heat in my compartment causing a short which at times causes my ECU to leave the injectors full open at medium to low load-what wire do I use? I reset the computer with the #1 fuse and the problem disappears or else I get out and yank the harness to the injectors..
What wire specification do I ask for when I get to the Parts Counter? How do i avoid PVC insulation which isnt that good, I hear.I found wire rated at 80 degrees C at Radio Shack. Is that good enough--I don't think so. Also where do I buy this wire, without having to go to some place really strange. Would Sears, pep Boys or Home Depot have it?
I would like to do this job so it looks very neat and invisible (i.e. like OEM)-does nay have any suggestions as to dressing the wire and where I can get the materials to do so?
?

If you want real automotive wire check these guys out.

Look under the supplies section.

avoid PVC insulation and look for Teflon insulation.............

try http://www.mcmaster.com they have a great variety of wire, a lot of which you can buy by the foot. Single and multi-conductor wire jacketed with PTFE or silicone will stand the heat really well. Get some shrink tubing too, to really finish the job off right.

hopefully, my advice is a lot better than my ability to type a web address, sorry! :rolleyes: search on #'s like 8219K57 or 7304K12 for example. This is PTFE hook up wire, good for 392F

WWW.Waytekwire.com has lots of good stuff but they have minimums so it may be more then you want.

I have been working on my own cars since about 1968 and later worked as a Diesel Mechanic for 18 years. I have never had an issues with the wires sold at the Auto Parts Chain stores in any of the vehicles I have worked on.

The only time I have used really high quality wire was when for 3 years I worked for a company that bought wire from an electrical company.

The main issue is to fix any fuel or oil leaks and keep the wire away from heat like the exhaust system.

My best guess for a typical local source of better quality wiring is NAPA (lots of professional shops do business with them) next would be a store that specializes in commercial marine stuff (when a boat or ship has issues when they are out on the water it can be serious).

Note local auto auto parts stores have only fair electrical connectors.

You da man!
The OP has been waiting for this info for only 12 years.

But, as you see people are still reading the thread and there for may or may not find the info useful. People might look up an old thread.

I found the info very useful.

As usual Frank offers up his minimally useful one liners.

A couple of points in this thread.

The Volvo wiring is the same as the bio degradable stuff found in similar year MB and Jaguar.

Teflon isn't what you want, it cold flows when tie wrapped / clamped resulting in insulation failure. It is useful in a very few locations like from the oxygen sensor to the plug but no farther.

Some insulation is made for use in electronic devices and has a very low melting point. Touch a soldering iron to the test wire and to OE wire in good condition and compare melt time.

And, I'm wondering why the OP was seeking electrical advice from those that shun electrically operated engines.

Carrameow, wonder where that guy is now he sure had some interesting adventures.
He moved for NJ (I think) to Seattle, Wa. into a HOA. That was for some interesting car repairs. LOL
