I'm installing an electric water pump right now, and in addition to wiring it to run when the ignition wire is hot, I'm using a stock Traction Control switch (momentary switch) to run the pump and the fans (on high) for track use.
Why the momentary switch instead of a rocker switch? 1) It's stock looking (IMG:http://www.frrax.com/rrforum/style_emoticons/default/smile.gif) 2) I have fears of flipping the switch accidentally one day and killing the battery. That's where the timer comes in. The GM defrost timer-relay will use a momentary pulse to energize the relay for 10 minutes on first press (then 5 every press after until the voltage is pulled from it). Had I wanted to elliminate the rear defrost grid in my convertible I could have just used the defrost switch as well with a simple wire splice... unfortunately I use that defroster in January. Soooo... does anyone have a HVAC control panel from a Firebird laying around? The solid-state timer-relay I need is built into the board, so a "replacement part" actually is the whole panel (IMG:http://www.frrax.com/rrforum/style_emoticons/default/tongue.gif) I know you wanta toss that crap you have laying around after building a race-duty monster...

I have a 96 TA that I'm adding an electric pump to and I've been looking for a timer relay to run the pump and fans for about 10 minutes after I shut the car down. I've looked all over the internet for commercial products and have found a few but they are not exactly what I'm looking for. I had thought about the defrost relays but I had not investigated them any further. If you got this to work, I would be really interested in the out come. John |
