NEEDED: Olds 307 engine wiring diagram

[454GrandPrix]

I've been helping a friend replace the dead 307 in his 1988 Oldsmobile Custom Cruiser with a Chevy 454. The new engine is in and entirely ready to go. We want to sort through the engine bay wiring so as to attach the few wires we need (for the gauges, etc) and remove ones that serve no purpose (everything related to the CCC, for example). I figure this engine wiring has got to be more or less identical to any 307-powered '87 G-Body, but my Google-fu can't turn one up online.

Anybody know where I can find one?

Maliburacing.com has wiring diagrams. The colors should all be the same per function, but may be in different locations Olds to Buick to Chevy.

You would likely be closer to use a harness from a Caprice, than a G body. The one thing I do know is the starter wires will need to be extended since the starter on a 307 is on the drivers side, 454 is on the passenger side.
