Relay Board Spare ports

Post by overdrive39 »

I am wiring my 502 RamJet and have become very confused about the relay board and the knock sensor and MAP sensor. Where do you place the sensor wire from the GM knock sensor conditioning box on the relay board also the GM MAP sensor (where does this go on the relay board). I have a four wire IAC, CTS, IAT, GM HEI8, 8 injectors, and a LC1Wideband controller, all have a neat place on the relay board. Am I missing something? :RTFM:
All help welcomed.
Thank you in advance.

The relay board doesn't have a dedicated knock terminal, but it should be possible to find a spot. How exactly was the MS modified for knock input?
