bypass EST
i've installed the holley pro strip annililator ignition on my '86 t/a 5.7l TPI. took the ignition module out. so the EST code is now tripped. the four wire connector has two not being used. they are an input and out put reference to the computer. what do i need to do to get the computer to think that it is working? i've tried to loop the wires and no go. i've tried looping the distributor pulse to the input. no go. i've tried pulse wire to the output wire. no go. the fourth wire is to the condensor. at least i can make my own timing curve now via the holley.
