Making the harness 2Now we will cut the smaller red wire provided with the kit into 4 lengths, 5", 6",7", and 8".
The wires are stripped on both ends, and the diodes are connected to one end as shown(line on diode to red wire). Solder and cover each diode connection with 1/8 " shrink tube.
Next slide the piece of 1.5" X 1/4" dia heat shrink that you cut from the ECM shrink tube over the 4 diode leads, and solder the 4 wires to the heavy red wire, then insulate with the short 1/4" shrink tube.

Installing the temp probes
|  | |
from the end of the ribbon cable, the first 3 wires of the ribbon (Brown,red, orange)will be peeled back to 3 inches below the splice point of the red wire and diodes.The brown wire will be separated from the red and orange, and pulled to the side. The red and orange and the yellow green ribbon(separate two wires)will be cut off just at the point where the red to diode splice was made.
The red and orange will be separated, and the green and yellow will be separated, and a 1" piece of 1/8" dia heat shrink placed over each of the 4 wires. The red wire from both temp probes will be connected to the red ribbon wire, the black wire from both temp probes, along with the short white with orange stripe wire, will be connected to the orange ribbon wire. The MPI temp probe(shorter) white wire will connect to the green ribbon wire, and finally the yellow ribbon wire will connect to the remaining white wire from the longer battery temp probe. After soldering, all splices will be covered with heat shrink and shrunk down. |
Final rear terminations
The temp probes will be what we pull on to get the harness through the car, so it is important that we properly strain relieve the fine ribbon wires during this next important step. Hold the diodes, and temp probes on the ribbon so they are all taunt.push the temp probe back towards the front of the harness about 1/4", to make the red/orange/yellow/green ribbon wires loose. Tape the whole bundle at that point, with the top of the diode splice heat shrink as the end point for the taping. Slide the 12" piece of 1/2" heat shrink so the end is flush with the tape, and shrink it. Next tape the whole end of the harness together so it is one long single unit, so it can be pulled through the car easily. |
Shrinking the central junction point
The 3/4" piece of shrink tube will now be centered on the taped up central junction point, and shrunk down. Your harness is now finished. Go install it. |
