manual wiring loom help

[giffo2010]

i'm doing an auto to manual conversion, and i will be swappin the auto ecu and harness for a t5 one.
just one question though, when i plug the ecu harness into the dash harness and the manual transmission the speedo and reverse lights should work or will i still have to do some rewiring in the interior?
and with the engine harness are all the plugs the same except for the transmission? so will the new harness just plug into everything in the engine + the transmission?

thanks in advance for all your help guys

Every thing should be fine. Thats why holden uses individual looms. That way its all plug and play. If you have the manual loom then all is sweet.

no, you'll have to rewire some stuff at the inhibitor switch.

1. bypass switch
2. connect reverse light wire at 4 pin plug to blue wire on power button wiring
