New Questions at bottom!
Okay, here's the deal. I started this engine swap almost two years ago. It's an 87 V6. The engine is either from an 86 or an 87, I can't recall which. I almost finished in time before I took off for College but didn't. I've hooked up everything I remembered but can't remember for these 9 things. It is also the wiring that was with the new engine. Please help me and please state the number of the picture you are refering to.


#1 The white and gray wire had a splicer on it and the only other wire that is stripped and available is the orange wire. Should I hook them together?


#2 This red wire that hooks to the battery. Doesn't it bolt down with the fusable links and such on the right side of the car?


#3 Where do these go?


#4 I need to hook this tube to the aftermarket K&N air filter tube to this pipe, right? Also the "clear" tube is plastic would that be fine that close to the engine using 3M L230-HT duct tape rated to 200 Degrees F wrapped around it a few layers?


#5 This ground wire that comes from the battery terminal wire is cut. What does it connect to?


#6 These are on the left side of the engine bay close to the gas line. Do they connect to anything?


#7 What about these?


#8 These and in the next picture are just hanging down by the catalytic convertor.


#9 More by the catalytic convertor.



Thanks very much. I'm trying to get all of this back together by Saturday night

#6 Those are the A/C hose connections, there's a hose assembly that runs from the compressor to those connections.

#8 The lower connector in that picture may go to the A/C compressor, or may be the O2 sensor, what color are the wires to those connectors?

#7 Are those vacuum lines? Normally vacuum lines are black, those look grey. Got a better picture?

#5 That used to have a ring terminal on it, and a screw through that terminal attached it to the battery tray near where the battery hold-down bolt goes.

#4 There is no duct tape that will last long in the engine compartment, it all turns to either goo or dust, or both, and becomes a fire hazard when it starts falling on the manifold. What do you have that tube hooked up to? There is normally a metal tube that runs from the hole in the forward valve cover to the intake snorkel (black ribbed thing), that's the PCV fresh air supply. It looks like you may have the pre-recall snorkel which didn't have the hole for the metal tube. Got closeups of both ends of that tube?

#3 Those relays go on a bracket screwed onto the firewall just below the glass just behind the driver's head.

The rest I can't help you with, though it's never a good idea to connect two different wire colors together in a stock harness.

1 - Open the harness up some more to see if the white wire has been spliced further back. Really need to figure out where it goes in the harness. White wire at the 500 would normally be for the tach (Pin C3). Please check the pin location of the orange wire to see what it is supposed to go to (orange is not normally a 500 connector wire color).
2 - The wire with eyelit and the other one to the far right in the pic go on the black plastic junction block directly below the 500 connector attached to the frame rail, directly in front of the strut tower.
3 - Those are the AC and Fuel Pump Relay and mount to the firewall directly behind the driver seat (and in front of the air filter housing about 2" below the rear glass.
4 - Need to see what the end of the tube is connected to (PVC or possibly vacuum to brake booster)
5 - Needed ring eyelit and attaches with a 10mm screw to the chassis between the battery and strut tower.
6 - AC lines from compressor.
7 - Those are vacuum lines that go to hard lines on the rear firewall and go to the evap canister/cruise.
8 - Both go to the backside of the AC compressor
9 - Goes to the AC clutch

Here is where the orange wire goes into the 500 connector




I traced the white one with a gray stripe back a bit and found that it was spliced to a pink or red (I can't tell) one. Should I splice them back together?




Here is the picture of where that tube was connected:

That tube needs to attach to the brake booster tube. It is a steel line that sticks out the firewall down where the shifter cables pass through. It normally has a rubber line with a fuel filter looking check valve assy attached to it.

There are small letters and numbers on the connector (around the edges) to idenfiy which location they orange wire is in, what is that location?

I didn't see numbers or letters anywhere on the male or female portions. Maybe they don't have any?

Isn't there a tube in the back where a tube is supposed to run to the aftermarket K&N intake?

Would the car still start without hooking them up?

TIA

There should be a metal tube attached to to the side of the engine that goes from the PVC valve on the front valve cover to the rubber air inlet tube.

I downloaded the schematics and it's E3 for sure and that one is supposed to be pink. Whoever worked on this harness was a dope. It comes from the engine harness pink, then it has a 3 inch piece of white and then to orange where it attaches to the C500.

Here is a good diagram with the pins labeled.
