What you need:
(2) 3 Amp Diode (EX: Radioshack 276-1144)
(1) 3/8 Female Spade Connector
(1) 3/8 Male Spade Connector
14 GA Wire
(4) Butt Connectors
Solder (preferred over butt connectors)
Soldering Iron (if using solder instead of crimp connections)
Heat shrink or Electrical Tape
Diagram:
This will allow you to add a high idle switch to your truck without cutting up your stock harness.
Gather your materials:
Add your Male spade to one end of the wire. The male spade will later connect to the engine harness (original high idle circuit). Crimp or solder. Heat shrink if you have it, or electrical tape.
Cut about two inches of wire and add your Diode. The BLACK end (NOT the stripe!) should face your Male connector you just added. This should preferably be a solder connection but use butt connectors if you must. Heat shrink or electrical tape when you are done.
Cut another two inch chunk, ALSO grab your remaining wire. Push BOTH of these wires into the female spade and attach (crimp or solder). Heatshrink or tape. The short piece is for the harness you are making, long piece goes into the cab and to your switch.
Now attach the piece you just made and the other with the diode. Should end up with something that looks like this. (But hopefully prettier, this was a quick hack job)
Now go out to your truck and connect to the existing wiring. Tie the wiring out of the way when you are done.
You can test for function by touching the long wire to your positive battery post. You should hear the idle solenoid click and hold the throttle open just like it normally does on a cold start. You should NOT hear the advance solenoid click. The end connecting to the stock harness should have no back feed at all, you should be able to touch it to ground and have nothing happen.
Run wire into cab, connect to switched +12V, and you are done.
High idle will work as it should on a cold start, and now you have the option to run it whenever you want without turning the cold advance on.
