Can anyone tell me if these connectors are OEM? They appear to be tach and vacuum gauge signals.

not oem

Thanks, yes looks like some one hacked off a connector that goes to gauge panel.


Seems like I remember a single row brown connector here?

Hey Shawn - I have two more 951 engine harnesses that were in a little worse shape than that one. Both of them have that connector intact though - it is a square red connector that hooks in under the dash.

Depends on the year. 86 cars without oil level sender had a 4 wire connector -- bright red square plastic with low tech terminals inside. Later cars had the one you are thinking of.

Thanks guys!

Here's how I did one if it helps-

What are you selling the harnesses for ($$$)?

I'd kinda like to do this myself... though rather than patch a bad one, I'd like to build a complete harness from scratch (fresh wire and all). I have some friends in good places and should be able to source most, if not all, the underhood connectors. I just need a harness to model the new one from - and I don't want to use my existing (functioning) harness that's currently in the car (cuz it works and I don't want to pull it, risk damaging it, and then not have a running car...)

Great thread. Pretty much exactly what I am doing.

All of the Bosch connectors, housings and boots up to six positions. The oddball VDO for the turbo temp sensor was not part of it, neither was the square red gauge connector.

I am pretty sure the group buy was for all new Bosch connectors for everything under the hood. Pretty much anything that was available, including new pins and a pin tool. I bought a full set and a couple other individual connectors including spare reference sensor connectors. I am pretty sure he ordered extra stuff, but can't speak on whether he would part with them. If you are really interested, I may part with the ones I bought as I will probably never get around to rebuilding my harness.

Thanks. I already ordered all the Bosch connectors from Ian at 944online.com.

So far I haven't seen anyone tackle replacing the ground wires. What's your plan here, Shawn? Are you going to keep the original wires?

Mine are too far gone, so I'm trying to figure out the best way to replace them. There are these odd pressure-weld joints in the middle of the harness that bring all the grounds together. I don't know how to reproduce these so I'm thinking I will simply run all the grounds to a ground bar mounted in the footwell. I'm still trying to figure out what gauge to use for the block/bellhousing grounds. Porsche used some bigass wire here, significantly bigger than seems necessary given what I understand the load to be (essentially the injectors, since the other loads are small by comparison). I may end up using multiple runs of AWG10.

You move fast on projects!

That is what I did also. Josh B has a couple more harnesses, PM him.

Mine are in pretty good shape. Think I will be keeping the original ground wires.

Yep, love being in the garage.
