Overhauled a manual EM harness
I bought a manual emmissions (em) harness off of Cloead (Bill ) recently with the intentions of stripping it down and making it into a Single turbo harness. I started working on it last night and stopped at 4:30am this morning. I was getting into it. It was completely stripped of all tape/loom. Any brittle wires were replaced. Well I just finished it and thought I'd share. What I left out is all the rats nest connectors/wires, the air pump wires, EGR, Double throttle, and included 4 color coded wires for future gauges like Oil psi, water temperature, oil temperature and a stand alone fan controller maybe. Having those extra wires there pays off later.
This is the 4th harness I've done and it's gotten way easier. Note that all the connectors are labeled.
Anyway here it is..

Nothing fancy needed here. Go to Lowes and get you some 3M tape in your choice of color. I used black and red. I like to do mine in front of the tv - multitasking. I spread out a sheet to keep from screwed up the floor, don some vinyl gloves ( oil/adhesive on the hands is no good ) and work with a bright light. I start on the cabin side of the large grommet and look for the oem tape seam. Start peeling. If it get stuck I use a single edged razor to carefully slice a seam to aid peeling. As you work outward you will run thru the gray sealant. Not a problem, just work the wires thru it.
When you come to a junction of wires you will notice a factory white tape. This was put there to hold the wiring junction in order for more tape later. When I hit one of these I cut the white tape off and add a black 3m tape to keep things in order. Otherwise you'll have wires everywhere and then you're hurtin'. You don't want to allow any of the wiring junctions to become messed up, when the harness is laid out on the engine things won't line back up.
You will notice some main wire headers, like the black/white solenoid 12v wire has a lot of splices covered in blue tape. When you cut out the rats nest, just take the associated b/w on back to a splice ( blue tape ) and cut if off there, back under the blue tape. Re-tape that with 3m good. I end up with 28 connectors total on the entire harness.
Before the next step take a contunuity meter and verify every outter harness connector with X-05, X-14, #3 and #4 ecu connectors. Better now and not later when it all taped up and on the car.
After everything is squared away and every unused wire snipped out, then retape the entire harness with 3m and then apply the summit convoluted loom in your choice of color and tape that over.
