The installation of the terminated engine harness is pretty straight-forward.
1.Mount all engine connectors.
2.Place VAG coils (not included) and connect to harness. wired for SHORT VAG coils!!!!
3.Connect all injector connections (JPT connectors).
4.Route harness thru firewall and mount MaxxECU.
5.Wire battery, power, ground, alternator and engine starter to 12-pin connector.
6.Wire extra connections like fuel pump, fan, wheel speeds, ethanol sensor etc to 16-pin connector.
Please note that REV1 (unmarked harness) pinout is mirrored, please check the printed labels on the cables which is correct!!
Note: Pinout is from the wiring side of the connector, not the factory pre-wired side.
