    The cigarette/cigar/power outlet is an iffy place for a power source since the positive lead is center of bottom of socket and barrel is ground. Maybe find a dedicated source from fuse box...

    If you have the relays wired-up then just connect them. Double check to see if your on the correct pin.

    Not that I know of, but if need be, I can swap mine out for a 8625 and load your bin. Not gonna happen today though, it would be several days before I had time.

    I'm fixing to go out and wire in a couple lights the ecu and do some more testing. It was getting too cold last night to do the wiring.

    looks like my volt meter must not had enough resistance or something. it appears to be working with the relay hooked up.

    now that is what i want to hear. glad you have it working. let us know the progress as i want to use the schematic i posted and have the ecm run the fans, engine, and the 60e.

    With yours C1 will go to E3 (Fan A), this will be high speed with both fans running. Connect C2 to E7 (Fan B), this will be low speed with just the right fan running.

    If you want to use the soft start for high speed, then replace the Cool Fan 1 Relay with the Hella solid state relay. The relay connections will be like this:
    wire B1 to pin 86
    wire C3 don't use
    connect pin 85 to ground
    wire B3 to pin 30
    wire C1 to pin 87

    you are the man. i have this saved to my camaro info folder. man i love this sight. but one question. in the diagram i posted when the first relay (or temp threshold is reached the fans come on low) the first relay hits the power on both fans but there is a croosover wire that causes them to run on about 50%, then when both relays ( second temp threshold is reached) both fans come on high. so will these grounds from the ecm come on consecutively, or is it one or the other.

    They will come on consecutively, but you need to keep in mind that this code may not work the same as the original code. You will need to play around with is some if you want to try and match the original operation. You may be able to achieve something similar with creative use of the different parameters. Your options are all open, with one exception, if you want to use the soft start then you have to use the solid state relay in the Cool Fan 1 Relay position, controlled with Fan A.

    Because the coolant flows through engine, out the back of the manifold, through the heater core, through the radiator, and finally back to pump, until the thermostat opens.
    This return provides the fastest warmup. Returning to radiator pulls even colder water into block. I have buses with oversized dual heaters so I have dealt with slow and poor warmup for years. OEM solution for mid '80s and '90s engines with aluminum wet flow intakes was to put heater connection in rear of manifold and ensure restrictors in intake gaskets covered rear coolant ports (coolant had to run from front of intake to rear before exiting) and to use heater outlet fitting with restrictor. I've brazed 3/8" washers to heater outlet fittings in the past to reduce coolant flow out of block. But if your intake gaskets are allowing coolant to enter manifold from rear of heads you'll never see proper warming.

If you'll like it, then it may find it's way into the Advance v275.xdf.

    Enjoy:
    O.K , I give up , I typed all of the HEX included in the code above into the Hex editor in T/P for my .bin . How do I get the functions included in the fan control XDF that 93V8S10 provided to show up in my bin on the T/P parameter tree ?

    Am I just missing something ?

    Thanks
