[QUOTE="Willie, post: 16260237, member: 14133"] As far as the add-on wiring, yes, the same. The only differences, if any, would be location of the factory components and possibly the wiring color. My suggestion if you haven't already, is to get factory wiring schematics for your year. You would use this as the basis for any and all electronic mods / add ons, etc. To add the manual IC pump override switch, I tee'd into the Dark Blue / Yellow wiring that runs from the pump relay to the PCM at the base of the relay. Run this new wire to the switch, and ground the other switch terminal. This is assuming your switch is NOT lighted, which makes this circuit as simple as can be. I used 22ga, multi-stranded wire. Okay, so assume you already have fans. We can wire these countless ways, depending on how you want them to work. On my car, I wired them to run when the pump is running AND I can also switch them on manually, as you've seen the switch for this in my pic. Can you describe what you want? In addition to my switches, I installed one LED for the pump and one for each fan. When lit, they tell me that the circuit is working and voltage is received at the pump / right side fan / left side fan. These LEDs work independently of my manual switches. For example, when the PCM commands the pump to run, thie LED lights, regardless of switch position. Purely not necessary but it sure helps when problem solving and also knowing that the pump and/or fans are running when cruising down the boulevard.... you certainly can't hear them.... I have two similar LED's that tell me the coolant fan is running on low or high speed also. Yes, if my description above isn't sufficient. Willie [/QUOTE]
