Code 43 ESC?

89 coupe... Can someone tell me where the Electronic Spark Control Module is? I have a code 43 and it leads to the ESC. I’ve search through my FSM but unable to find anywhere were it tells you where it is.

It's on the blower motor housing right by the washer bottle.

Thanks Josh, I thought that may be it but didn't want to start probing it without knowing for sure.

Should you be able to wiggle the wire connection end of the knock sensor or should it be in a fixed position? I’m assuming it should be in a fixed position?
