I searched already, but this whole wiring thing is new to me. I have an 89 LX, and have done the carbed 351W swap. Recently, I took out the computer and all the associated wiring. I had been using the stock ignition coil wire to power the new coil, and power the ignition system. Now that it is gone, I dont know what to splice into. I have most of the chassis harness still, would any of those wires be good? Thanks for any replies.

Does anyone know of a specific wire that will have 12 volts and can handle the ignition system?

Do what I did, just take off the steering column cover and find out which wire does what (using a multimeter or test light), then splice into them. This is off memory (not very good source for me) but check the large grey wire with the yellow stripe, I think you can also find it where the computer used to sit. Check to see when it has power... Again my memory doesn't serve me well sometimes. I'm not sure but that wire might work but I have the feeling that it doesn't have power when the key is in "start" position, only in "run" which won't work too well for ignition

When I searched the Corral, I saw the grey/yellow wire mentioned. I'll go check it out. Thanks.
