mitsubishi challenger

kman:
I was talking to a guy in Narrabrai who was towing a very large van with a new Challenger. He said it towed very well. I have a Pajero and it tows like a dream (not a nightmare either!), but that is a 3.2L engine. not the 2.5L.


Troopie:
How did you modify the controls to eliminate the centre diff lock? What was involved?

V8 troopie, could you tell us how you did this mod ??

I have a need for this sort of mod to get my van up my driveway !!

Well, the auto freewheel lockers are vacuum operated. The valves for these are located behind the drivers side front wheel, hard to get at unless taking the wheel off.
Even harder is to figure out which of the 3 valves (the third operates the front diff locker) is associated, I followed the air lines back to the front diff, inside which are the freewheel lockers.
Once the valves were identified the wires controlling them were cut and routed via a suitable relay (located in a dust proof box under the bonnet). This relay, when not energised, connects the vac valves just as they were originally.
A switch in the cabin energises the relay and the vac valves no longer operate, even if the computer says so when low range 4WD is engaged.

I have tried to fool the computer by an extra set of relay contacts simulating the vac relay coil resistance even when its disabled, to stop that flashing light on the dash. But the computer is too smart for that I think.
Anyway, the mod works fine and I have LO range in two wheel drive available. A light on the cabin switch reminds me its on.

Its not an easy mod, would only recommend it for people very familiar with car wiring @ relay controls.
