so i have a 6AL ignition sitting around from when i had my 85 mustang. i've seen a lot of threads about it on here, just had a couple of quick questions.

first i know they sell a harness for it so no problem there. when you hook everything up, does it affect the computer or stock ignition module in anyway? how does the comptuer tell the box to retard the timing when it detects knock? i have the lt4 knock sensor and module.

so basicly is it just plug and play or do i have to program anything into the comp?

this is obd1 lt1 motor
