Installation
The installation of the terminated engine harness is pretty straight-forward.
1.Mount all engine connectors, alternator and engine starter.
2.Place VAG coils (not included) and connect to harness. NOTE: wired for SHORT VAG coils!!!!
3.Drill a 54mm hole in the firewall for harness bushing.
4.Route harness thru firewall and mount MaxxECU. Mount position is very dependent on engine placement and vehicle model.
5.Connect +12V with external relay and fused (15A) to the extra 12-pin connector, pin 9.
6.Connect +12V with external relay and fused (15A or more depending on coils) to the extra 12-pin connector, pin 10.
7.Connect engine ground (brown wire) on cylinder head.
8.Connect alternator (pin 11 on 12-pin connector) to +12V ignition (in serial with a charge bulb).
9.Connect starter trigger (pin 5 on 12-pin connector) to start button (+12V).
10.Connect fuel pump, fan and other outputs to available GP Ouput (GPO).
11.Install optional external IAT (highly recommended).
12-pin connector (seen from the wire side)
Note: Pinout is from the wiring side of the connector, not the factory pre-wired side.
