Wiring a 2nd gen coils on 1st gen
 

I am in need of some technical help...
I have a TII swapped GSL-SE that was blow-thru with a Holley that I am switching back to FI and I have been installing a Microtech LT-8S ECU for the last week. I am at the point where I need to wire in the TII coils BUT don't know how. I am using the CAS from the TII and got rid of my dizzy with ignitors. I am still using the SE harness so I need to know which wires go where to make these coils work. If anyone could shed some light it would be GREATLY appreciated.

Thanks

It is the same as wiring it up in a 2nd gen. But you will need to provide a switched 12V source to the coil power wire (black I think, check the 2nd gen FSM).

Yes, I have that much figured out...
What I was refering to was where can I get the switched source from on my SE as well as where is the tach signal now going to come from?

Thanks

Get the tach signal (for the dash tach) from the trailing coil. Yellow/blue wire.

There are many convenient switched 12V sources. I generally grab it from the actual key switch and use it to switch a master relay for the EFI system when I do 1st gen retrofits.

Thanks... will try it out tomorrow..

You can use the Thick Black white wire used for the original coil packs.

BUt you say you have GSL-SE.

Wouldnt you already have these coil packs? Or did your GSL-SE engines come with dizzy?

GSL-SE came with dizzy and regular barrel type coils...

Then use your regular black white + coil wires.
