I have located my ECU on my 88 bronco and found 2 codes. The first more obvious one is 8PZ with a smaller font F directly below the "Z". The other is 7L06 (zero not O).

I have 302 with automatic/overdrive with an air intake, throttle body spacer, long tube headers and true dual exhaust. Just thought that was worth mentioning.

Also, I would like to get the kill switch, is there any problem with that?

 

F8PZ means its a part for an 88, not the same as the PCM code. The 7L06 is part of the part number. The PCM code will be on a white sticker on the box. The sticker is the size of a postage stamp and is on the back side of the box (the side opposite the wiring harness connector).
