anyone know of a way to hook up a msd start/retard control to a lt1. where would you get the input from.i have the instal instructions but it doesnt list a opti spark. already have a msd 6al with a 2 step installed, just need to know how to hook it up so i can retard the timing for the nitrous.

 

You can cut it in to the coil wires or buy thr plug in play harness for $30.00. I would get the harness.

 

have the harness already in

 

I have a MSD Multi-Step Retard and it just hooked into the wiring harness to the MSD 6A.

 

yea,should have read the instructions a little closer.
