2.9i v6 sierra engine wiring loom - davepro
When I removed the engine wiring for installation in different car it came in four parts.
1/ main engine loom in engine bay that passes through bulkhead on passenger side and connects to ECU and also has three connectors to link into main
car loom.
 
Main engine loom
2/ relay loom that is linked to '1' above by one of the three connectors.
 
relay loom
3/ dashboard and reference loom that connects to the ignition switch for power and also connects to '1' by one of the three connectors. From
here the wiring goes across dash to dashboard to link in with gauges/warning light display. One cable goes through drivers side bulkhead, alongside
engine, across front of car and is negative coil connector.
 
dash - reference - loom
4/ Fuel pump and inertia switch wiring passes from relay under bonnet on drivers side, crosses dash then goes down passenger sill to boot floor, drops
to inertia switch in spare wheel well before connecting to fuel pump underneath. earth screws to just infront of passenger door in front footwell.

Have fun taking it all out - I did!
Davepro - Photos are reasonably large but let me know if you need any more detail.
If at first you don't succeed, hide all evidence you ever tried!
