Today I rewired my harness to accept Low Impedance Denso 550/720cc injectors. I have a 87 Base in which I am installing a Jspec S5 TII motor along with Jspec S5 TII LIM/UIM. The front cover is from S4 TII as well as the ECU, engine wiring harness, all sensors, and TB.

I wanted to replace the old S5 injector clips which had already been replaced to accept the S5 injectors, which are high impedance injectors.

I know that placing the resistor closest to the ECU is preferred, but I do not feel comforatble in my electrical skills to complete such a task successfully. The reason this is the preferred method is to protect the resistor itself from the engine heat, as well as the vibration. As you read along this post you will see what measures I took to help protect the resistor from these two enemies.

In the first pic you can see the parts I used for the swap. I purchased 4 - 10watt/10 ohm rsistors from Radio Shack, which look like little white bricks with wires sticking out of both ends and 4 new S5 injector clips from RP.

In the second picture you can see the 2 - 550cc (purple) and 2 - 720cc (blue) Denso low impedance injectors which require the use of the S5 injector clips.

The third picture illustrates the old S5 injector clip prior to removal.

The fourth picture illustrates the replacement injector clip and the 10w/10ohm resistor from Radio Shack.

The fifth picture illustrates the 10w/10 ohm spliced into the red/black wire of the injector clip. I basically wrapped the wire around the wire that I had stripped.


Thanx

The sixth picture illustrates the 10w/10 ohm resistor soldered into place.

The seventh picture illustrates 12/14 guage shrink-tubing used before and after the resistor itself.

The eighth picture illustrates 10 guage shrink-tubing used to cover the resistor itself.

The ninth, and final picture, illustrates the Thermo-Tec thermo sleeve used to cover the wiring, resistor, and shrink-tubing

Thanx
