Converting to DIS(coil packs) on a 2.3L Runs now

November 10, 2011, 08:59:56 PM

I have an '88 mustang with a complete '92 motor(both automatics). I removed the DIS wires(removed the pins from the connectors) from a '92 2.3l harness. I'm confused on this "CID" wire, because the notes I have say it isn't used, but needed for the EEC to control timing???

Here is the old write up on the subject

I didn't use it when I did the DIS install on my 2.3T Ranger. The turbo ECU's didn't use CID. Check your wiring for the 88 ECU. If it doesn't call for it, don't use it.

So just 3 wires on the crank position sensor need to be connected? Do I put nothing in its place in the plug? Does the icm need a 12v crank signal?

The notes on the tach resistor apply to the XR4Ti. The DPI should also not be needed, since you're not running a dual plug head.

It's been YEARS since I did the swap.

I remember that whole thing. It was pretty cutting edge back then!

Actually, I am!

Well, then that diagram should have you covered for the TFI to DIS swap on your 88's harness. Again, check your '88 ECU pin-outs on that CID, but you shouldn't need it.

Already did and there's not one. Right now it still won't start. I have it wired exactly like the schematic. For some reason I have 12.5v going into the icm, but 10.05v leaving the coils??

Do you have the DIS module grounded? I'm guessing so, if you have it properly mounted.

Yes, and i have the Or/ red stripe wire going to the IGN gnd wire.

10V leaving the coils? Where are you getting your coil power from? It should come from the same source as your 12V to the #1 on the DIS module. The DIS module grounds the coils.

If you look on my pic, 12v(red w/green stripe) comes from the coil pack wiring. Then there are 2 extra wires that i fed to the 12v side of my factory coil connector.

Kinda hard to see wire colors in your pic.

I dunno, man. Are all your engine/chassis grounds in place?

Yes, all grounds are connected. Maybe this pic will help.

I can't really think of much else.

Do you still have the CID going to the DIS module? The splice that goes off to the ECU isn't needed, but it still needs to be connected to the DIS module.
