Would like to get some pictures of the wiring on a 1994 TBI engine (or similar years). I bought a Mastercraft with a rebuilt engine but the wiring is a mess. Would like to use these pictures to get back to factory set up.

Thanks
Brian

Yeah, where exactly do you need? I have the same thing you have. 94 Indmar 350 TBI with 275 HP.

Back of the engine would be great. A close up of where the wires connect into the back of the engine.

I hope these help...., I suggest getting the clumers manual - it has wiring diagrams in it.

Most of the wires are casings... hope these help.

Thanks again for the pictures. I got a chance to look at mine tonight and my wires are a mess. Will need to get some new wire loom and spend a few hours organizing and rerouting wires.

One thing I noticed. My 1994 350 TBI had the brain box down on the side of the engine. I know they offered a relocation kit to move it. Your pictures show it on top. I think the idea was to move it to a cooler location on the engine.

My brain box looks to be in the lower location as well.

My dysfunctional brain box is also still on the lower side.

I thought that only happens when the fluid runs that way... :D:D:D:D

Dysfunctional meaning that one of the TBI injector drivers is defective and I am running both of my injectors off of one driver. Its a better option than forking out almost $800 for a new Brain Box. :D

Thanks

Hey DoubleD what's the hose coming off your riser drain plug?

Interesting how the brain box can be moved to such different place in one model year. from under a riser to on top of the engine.

I added those to drain the water from the jackets with the twist of a knob.
