Cg power window conversion

So I've bought all of the parts needed, door cards, motors, regulators etc. I've installed all of that. But they still don't seem to work.

The engine compartment has the correct fuse in it. And the actuator still triggers in all doors when I lock the car. I've got no idea what to try next. I can't find any fuses needed under the dash either.

Does anyone have any idea what to try?
 
Pretty sure there is a relay that needs to be plugged in under the dash. I will confirm in a few hours sheen u get to work.
Relay in located on the interior fuse box from memory.
 
Test your Earth connections on switches & motors. Then do the same on the power supply to switches & motors. You should find a break in one or more of the Earth or supply circuits. (NB - if there's a break in the switching circuit, resolve first and then retest the motor side) Trace the wiring back to the nearest break point(fuse block, relay, splice, junction box ect) and the test there. Trace back until you find the break & repair/fit components as neccasary. You may need the factory wiring diagrams to help out - there's a copy in the CH section I beleive or a few over the internet in various sources.

Let us know how you go/what the cause is - it'll be good for future info! Best of luck

Totally correct, you will need a power and earth connection before anything will work, you have to start somewhere so test that you have 12v power at the main switch distribution block on the door, if not work your way back thru the harness / relay to confirm power connection, then go from there.

So it turns out there's a relay missing under the dash, however the diagram for the fuses and relays doesn't say what a certain row of relays are. Part number mr588567
