TTT- I'm using stock ECU...well Rtek but, you get the point. Before my engine goes back in I'm replacing any suspect areas.

There's probably going to be more suspect area's than you think on a 25 year old harness. I've run into issues where the copper gets so brittle that I've broken it crimping butt connectors in, and then wrapping the entire chassis harness. Infact, hours before I was getting ready to leave on my epic road adventure, I noticed my front markers were out. Turned out to be a buttsplice that broke the wires and was only making intermittat contact. Pulled the bumper, fender and unwrapped most of the chassis harness hunting down that break. Sucked balls. Think of what might happen if that happens with say an injector on a boosted engine..... pop goes the rotary

Agreed. I'm going over everything. It's been an ongoing battle ever since I started tweeking things from having my swap done a few years ago. The guy who did my wiring for my TPS, to extend the N/A plugs to meet where the turbo wiring should meet.....well lets just say it was subpar. I'll post up pics for your shock and amusement later tonight.

When it comes to wiring, very little shocks me anymore.... it just amuzes.... sorry it happened to you though.

Just makes me wonder how many mytery fails are due to poor wiring

This was what I found after I started having engine problems shortly after my swap. The fuzzy picture is a cheap speaker wire someone used as a patch. Not only was it the cheapest of wire you could imagine, but the copper was corroded from one end to the other. All the dark area inside the insulation and also on the center area of the crimp is corrosion. The wire was corroded enough that the corrosion bled thru the crimp. The wire spliced in looked like it sat in the bottom of a damp trunk for sometime BEFORE it was used.


The other problems I had with almost every crimp the person made was that they didn't trim the insulation back far enough on just about any of the crimps. I had a few crimps that came apart in my hands while trying to test and adjust my TPS.


This is my replacement of the bad TPS. I swapped some from an N/A bracket to a turbo bracket and went over all the splices with solder.

This is a little more on topic. I was trying to replace my water thermosensor plug on the back of the waterpump housing. I have what I thought were two spare S5 N/A harnesses to steal parts from. At first I thought this was a water thermosensor plug...but the notches are on the opposite side.


I'm thinking of taking a dremel to it and simply making a notch.

Can anyone help me with a description of these terminals/connectors? It's from a S5 Thermosensor plug. Rather than splice some old wires into my harness I'd prefer to get new connectors and use new wiring.



I'd also love to find a new thermosensor plug like the previous post. But I'm having trouble with what to put in my searches on Mouser and similar sites. It's rectangular, female, two position, green. If anyone can help with how to narrow my search I'd be very grateful.
