Hi guys
i have replaced my 3.5 carb with a serpentine hotwire. But having a few problems wiring.
WHITE/ PURPLE live feed to the fuel pump.
LARGE BROWN in engine bay constant live from battery
BROWN/LIGHT GREEN constant live
WHITE/GREEN small wire live when ignition is on.
I have the white and green fused and it keeps blowing the relays clicked first time i powered it up breifly before it popped a 15 amp.
Any ideas I think the wiring is slightly different on the serp hotwire than the vee belt.

There are several posts containing wiring diagrams but PM me your e-mail address and I'll send you one plus a spreadsheet of ECU connections.

Mmmm i hate electrics.
Maybe its the BROWN/LIGHT GREEN thats wrong dont see one on yours Dave but its a big 27amp wire.
Think i need to print off all the info i have and have a rethink.
I thought i had earthed all the blacks maybe one has a trace wire i didnt notice
