Nitrous Veterans, please help...
Nitrous Veterans, please help... I have an HSW harris speed works Air to fuel, timing module. But sadly no diagram or start point for it.
I was told its plug and play, but there some type of 4 point relay i need to be connected to, according to the person who sold it to me.
Can someone please help me Figure it out, and let me know where the 4point relay is.
I tried doing a search, but it seems like HSW is no longer in business.
Thx

You only need the tach if your using the top end fueling feature...right from the instructions with mine "white wire for tach is optional. If not used then the top end fueling feature is still useable, but will be based off airflow and not rpm. Connect BLUE wire to triggering device(window switch, tos/wot switch etc...connect BROWN wire to the ground on the relay that controls the solenoids. For LS1 applications the GRAY wire needs to be spliced into the tan wire on IAT sensor..." Hope tgat helps

if you still have the instruction manual...any way you can scan it and post it?
Lots of folks still have the unit would be nice to have an online reference to the instructions
