1. There is a single wire running off the power steering pump...what is its purpose?

2. Wish i could get a pic and i can tomorrow if its needed but on the water neck there is a metal male connector...what is it for?

 

yeah i also need to know where to get one i ripped mine out too by accident and now that little spiky metal thingy is all bent up so i just want to get a new one

 

which one did you rip out by accident? I ripped the one thats on the power steering pump out by accident.

 

The wire to the PS pump tells the ECU to bump the idle so that you don't kill the engine while parallel parking.

 

damn i guess ill figure out a way to fix that one..

now for #2

 

BUMP for needing to know what #2 is.

#1 has been fixed.

 

no one knows???

 

on what water neck?

 

ok i guess a better way of describing it..its on the front of the thermostat housing right beside the stock turbo coolant line.

 

It is probably a water temp sensor...

 

there is a water temp sensnor on the the back. Im hoping this one is not a water temp sensor because there is literally no plug for it any where. it almost looks like a ground. Its a flat piece of metal. only other thing in the entire engine bay that looks like it is the same thing on the starter that i believe is a ground.

 

the one in back (towards firewall) is the coolant temp sensor, and the smaller one up front is the temperature sending unit.

 

Temp sensing unit...can you explain? And I don't have a plug anywhere on the harness, everything else is there except this. No cut wires or anything..

 

struggling to attach the link.....

if it doesn't come through as a link, go to autocenter.net, type in the vehicle and drill down to the illustrations of the parts.

ie, Evo, cooling, radiator and components, sending unit, water temp, view illustration. The harness should have a single spade plug, just like on the power steering pump.

 

Yeah definitly not on harness. But your saying it's one single wire right? If so I'll try and figure out the pin out on ecu and run a wire and splice at ecu.
