Forgot to mention on my sprayer power is supplied from a 12v source but the earth is from
ecu (
ecu triggers earth to activate sprayer)as it supples ground to compleat the circuit, but it is not the ground from the sx loom, rather confusing hence why I paid someone to do it who known the inner workings, easier and risk of damaging
ecu zero due to opartor error..(May or may not make any sense had a few beers after work today)
