[QUOTE="Willie, post: 16261641, member: 14133"] I'll start in reverse order; I will answer your last question first. >> A labor of love! It started with a plan of EVERYTHING I wanted to do. Believe me, there's much much more than just the above. I'll share my center console "stuff". You'll most likely say, "What is all that?" What I really need to do is create my own "user's manual" so that whoever inherits my car will know what I've done and how I did it... [ATTACH=full]1591246[/ATTACH] and..... >> [ATTACH=full]1591247[/ATTACH] But for now, let's stick to just this subject matter. Locate the IC pump relay. Yours may not be where mine is, so you'll have to do some digging. The relay will have 4 wires. One of them is the return to the PCM. On my 2008, it is Dark Blue / Yellow. Don't know about yours. When I say "tee", I mean splice a new wire into it, leaving the factory wire intact. The other end of the new wire connects to your turn-on switch. Ground the other switch terminal. This will will turn on the pump when the ignition is "On" only. So if you leave this switch in the on position and forget to turn it off when you shut down the engine, no big deal. The pump will not run. I need to ask you a question. If you wire a turn-on switch for the pump as I describe above, turning this switch On obviously turns on the pump with ignition On. You also have your HE fans connected so they turn on when the pump runs. So, when you turn on the pump with your new switch, it will also turn on the fans. You don't need a switch for just the fans... unless you want one to control just the fans. Do you want this or is the one switch for both work for you? Simple! For example, an LED for the pump. >> Tee (splice) a new 22-ga wire to the pump's power wire. Connect the other end of this wire to the positive on the LED. Ground the other LED terminal. BUT.... you will have to install a resistor on either of the two LED wires. It does not matter which and resistors are not directional so they can be installed either way. The resistor's resistance determines the brightness of the LED, so you'll have to experiment. Pick up a pack of 1/8-watt resistors, say from 100 ohms up to 60,000 ohms, give or take. Maybe a 100, 660, 1000, 10000, 30000 and a 64000... something like that. Also, when you experiment with different resistances and different colored LED's, you'll notice that some colors are brighter than others with the same resistor. So the resistor you choose is what works for YOU. Just remember NOT to power up an LED without a resistor. You'll fry the LED in a millisecond..! To wire up an LED for the fans, do it the same way. Pick either fan's power wire, splice into it and use it for the LED... Willie [/QUOTE]
