I need info on installing a Crane TRC-1

[Tiago]

I know few of u have one of these. The powerdyne instructions had what wires to tap into but I can't find anything. I need to know which wire on the coil assembly is the ignition timing signal wire?

Im actually putting it on
the 3.4 but I dont think anyone has done that before. If I can find what wire it is on teh 3.8 I can "translate"

Is it one of the ones here?

They list in pdf format the instructions for the TRC-1 here:

What do you mean by the signal wire? The wires that ground each individual coil? The only other wire going to the actual ignition modual is the one from the crank sensor, and then the one that the computer feeds it.

I have the factory manuals for my car so I should be able to find whatever wire you're looking for.

On the 3.8, the white wire is the trigger/signal wire.

not the coil wires


there IS a single wire that goes to the IGN CTRL module (thingy beneath the coils) that controls teh timing.

Looking at hte wiring diagrams I think it is the pink wire on one of the plugs that only has 2 wires.

Yeah, the white wire is the trigger wire. It's the timing signal from the pcm. The ICM will distribute that signal to the appropriate coil. If you intercept that wire with the TRC, then you will be retarding all 3 coils in one fell swoop.

I asked around a few months ago on this same issue.

Ok, there's 3 connectors going to the ignition modual. One has 2 positions, one has 3 positions and one has 6 positions.

For the one with two positions, one is ground the other is +12(black and pink respectivly).

For the one with 3 positions, the two outside positions go straight to the 3x crank position sensor. This is the backup/preliminary timing signal. The middle posistion is ground. Those two outside wires are yellow and purple.

For the last, 6 position connector in order are: tan/black is the ignition control bypass signal. I think when this is high, the ignition modual ignores the signal coming from the 3x crank sensor and uses the signal coming from the PCM. The next wire is this signal. It is a white wire and it is the ignition control wire. I'm assumming it's a digital signal on this wire since it has the control for all 3 coils encodded on it. The third wire is another wire white which goes to the tach. The fourth position isn't used. The fifth position has a light blue/black wire and it is the high reference signal from the 3x crank sensor. Teh sixth position is the 3x low reference.

So it looks like that 1st white wire(second wire from one of the ends) is the one you're looking for.

That thing must be able to interpret that digital signal. That's surprizing to me since I would think it would look way different from car to car.

Hope this helps.

white wire eh? dammit. I can't even see the plugs I was just gonna discect the harness leading up there because I can see that ;)

but there are 2 white wires there. I have one tapped for my shift light and that works. Is it safe to say that the other one MUST be the timing signal? or could the timing signal also operate my shift light/give a rpm reading?

[John_D.]

The timing signal could operate the shift light... So I don't think you can conclude anything from that.
