CA18DET Installation 8 - Wiring

So time to start working
out how to wire this baby up
First up I made a home for the loom (through the
firewall, so the EFI computer can live in the cabin)
Additional to the CA18
EFI loom I have to power the fuel pumps, give the ECU a Battery 12V, and
Ignition switch. I also need to connect starter motor, alternator, knock
sensor, Datsun loom (headlights etc..), Oil pressure, Charge light. Then
I need to work out all the dash intruments.
The loom I have has been modified a bit already removing
some of the irrelevant wiring - I bought it second hand that way so not
entirely sure what is missing, anyway there is a wire of a relay that
will power fuel pumps, I send this into the cabin and then run wire down
to both fuel pumps to give them power.
Earth both fuel pumps to the body.
Next 12V source to ECU - with a fuseable link in between
- as I think blowing up ECU's is pretty uncool. Soldered one side - the
other connects to the 12V from the kill switch.
Connect IGN into 1200 IGN switch - found the easiest was
to tap the IGN wire in the engine bay - was pretty close by
Sent big +ve cable from battery to the starter motor -
and the signal wire from the ignition switch. Also on the starter I've
powered the entire 1200 loom of the Batt +ve pole....as there is no
battery in the engine bay anymore.
