Ae86 4ac-4age - Questions - Wiring Loom

[AE3SGTE]

Picked up a FWD AE82 bigport with ecu and loom and have a few question for those who know or have done a similar conversion.

I was checking out my loom today and I notice that the 14P plug is missing?
I definitely need this plug yeah?
What is it used for?


Also mounted to the ECU cradle is an open circuit relay? i think
This one

What is this used for?

There is no loom or plugs supplied to fit this...do I need it?

Where should I mount the ECU?
Where is factory ECU mounted?

I imagine I will have more questions as I go along.
Any help will be of much appreciation!

Can I get away with using my ADM Sprinter fuse box or will I have to get an AE82 one?

I was looking at the RWD 4AC water pump vs FWD, and noted that the FWD has no thermostat supplied, however the RWD 4AC water pump rear housing has a thermostat. The only thing is that the out let will not clear the ALT.

FWD 4AC/4AGEs have remote thermostat housings (they sit on top of the gearbox), RWD ones have them built-in to the water-pump housing.

Yep, thanks for clearing that up...
I think I'll be using the RWD 4AC rear water pump thermostat housing.

Can anyone help out with my loom questions?

The 3rd plug is all the body electrics, so the plug is part of the dash loom.
It has that you'll need, Batt feeds, Ign feed, Check engine light, Fuel pump relay output,
speed sensor, etc.

The circuit opening relay IS the fuel pump relay.
Has 5 wires Batt, Start feed, Earth, Pump out, and signal from ECU.
