What wires are these?7MGTE

[aloshan]

Hey guys

So I've basically eliminated everything from my gearbox shifting incorrectly at lower speeds.I've changed the no.1 speed sensor,installed new solenoids in my a340e and replaced the dash with a new one. I'm still throwing code 61 which is no.2 speed sensor on the transmission. Ive checked the wires and they seem to be okay however the person who built my car had to fabricate a wire harness. I'm unable to get hold of him to find out exactly what was fabricated.

Ive found two connectors in my bay that seem to be part of the harness leading to the speed sensor. Can anyone identify them?

They don't plug into each other and I'm not sure what they could be

thanks in advance for any help.

The brown one looks like the connector for the VSV on your vacuum piping below the intake manifold. And, the grey one..........everybody asks what that one is for! I don't know if I've ever seen a true explanation, but it is said you will do fine without it

If the grey one has a red yellow and black wire going to it it's for abs

That could explain why it is OK to leave it unplugged. Maybe all harnesses are come with it in case the car has ABS installed at the dealership.

Brown is for EGR and hot start VSV's. Grey connector is for ABS.
