Hi, Would appreciate some help with a couple wiring questions on a '96 Neon coupe.

We've lost power to the interior light circuit (pink wire) somewhere between the engine compartment and the dome light (trunk is out too). Does anyone know how this wire is routed and if there is a connector in the dash area I should check?

Also there is a ground stap attached to the body near the front passenger side strut tower that was not re-attached to the engine. Can someone please let me know where it is supposed to bolt on?

Thanks in advance for any help with these!

As far as the ground strap, it goes to 1 of the exhaust manifold bolts. Your car nust have the headgasket replaced and they forgot to reconnect it. Hope this helps.

 

Thanks for the info. I suspected the strap was off for the same reason you suggest. Car runs well but leaks a quart of oil every 700 miles or so .... from about every place but the head gasket.

 

A common leaky spot that I have heard of is the oil pressure sending unit. It should be located on the back of the engine block towards the firewall, under the exhaust manifold/header close to the transmission on the drivers side. If this is where it is leaking from, just remove the sending unit and wrap the threads with teflon tape and put it back in.

 

Got an answer on the dome light from a trip to the salvage yard last weekend. The pink wire to the dome and trunk lights enters the bundle that runs along the outer driver's side floor. It splits out at the C pillar and runs across the rear deck to the trunk light. The pink wire continues from the trunk light back up the left C pillar to the dome light.

Our circuit failed due to moisture under the carpet about where the driver's left foot usually sits. The mositure combined with a constant 12V on the pink wire caused about 6 inches of the copper to corrode away.

Successfully spliced in a repair and will hunt for the souce of the water another day.

Thanks!
