    Same type of wiring diagram as listed above, and finding settings?

    Yes, the wiring diagram & settings are the same for both.

    The thing to remember is that an HP & Dominator are the same software (and some of the same hardware).
    The only differences are that you get more Inputs & Outputs with the Dominator (which allows for things like transmission control and DBW throttle control and a 2nd WBO2 sensor). Otherwise, they are exactly identical.

    Yes, the HP & Dominator ECUs share the same EFI software (aside from Transmission, DBW, Multi-Map Selector, dual WBO2 Sensors & additional I/O).

    Does it matters whether blue or orange wires from 554-111 solid state relay are reversed (use either)?
    Or is there a particular wire for +12V, and one for PWM +12V?
    Obviously the black/yellow wire is you PWM- Output from ECU.
    Just wiring up bump box now, as per Scott's 3 Relay diagram.
    Cheers, Tim

    Yes.

    Yes, the orange wire with the fuse, connects to the battery positive terminal.

    Thanks Danny. I did try entering part number in the Technical Resource Library, but wouldn't let me select any other page than number 1 in my search. I overlooked the fact that nitrous wiring was in the main HP & Dominator documentation. Cheers, Tim

    The instructions are also supplied in the box, but I understand the box may have been discarded.

    Does anyone happen to know what frequency the BTE Powerglide Transbrake solenoids like? It's the screw-in style, not that it makes a difference. Having the hardest time getting this thing to bump. 3 relay system.

    As I told you over the phone, they do not have a set frequency or PWM value. You just have to play with it.
    Some cars will never be smooth, depends on how much power it's making, how tight the converter is, how good your relays are, which solenoid, which valve body...A LOT OF VARIABLES. There is no set value that works on every car, and some solenoids just don't react fast enough to be smooth anyways.
