MC-12 DDEC wiring harness

[scott332]

Does anybody know where the DDEC wiring harness in a MCI MC-12 ends in the front of the bus?  The DDEC harness is separate from the MCI harness.  It starts in the rear at the DDEC computer on the engine, it is in it's own harness.  It is routed beside the rear junction box, then goes forward to the rear storage compartment where it goes into the center wire chase.  I can't find where the harness stops in the front.  I found the wires I'm looking for in the rear storage compartment, but I'd like to find where the wires are in the front to make it a cleaner install.  I'm working on hooking up cruise control, and need these wires to hook up to the switches in the dash.

Has to be a MCI responsibility so it should be in your manual the DDC responsibility ends at ECU does it have a plug ?

The engine end has a plug, I don't know if the harness on the front end has a plug of not. The manual doesn't show where harnesses are routed. It just says the wires end up in the front.

The CC wire in my MC 12 came out in the electric panel on the drivers side up front.  All of the wires go in a conduit to the center of the bus and the conduit ends about 5 ft from the drivers compartment.  They put foam in the conduit so they are hard to get out.  My MC 12 had a box on the left side of the dash that controlled the curse speed.  The Jake and fast idle were on the left side of the driver.

I found it. I traced the wires from the engine override switch in the dash.  There is a junction box I never noticed before above the windshield washer bottle. There are over a dozen studs in there all of them are for the DDEC wires from the engine.
