Knock Sensor Circuitry #s - ZR-1 Net Registry Forums

In connection w my saga of chasing away detonation, I had a discussion w
Marc Haibeck regarding identification of correct KS circuitry for our ZRs. Also its a good way of determining we are looking at an LT5 prom and not an L98 or LT1/4. Here are the numbers that should be stamped on the face of the piggyback circuit board for the Knock Sensor. These are for 91-92 ZRs, since the 93-95 motors use different sensors for determining knock and the 90s use an outboard module.

1068008
1064306
1065180
1069175
1060303
2061252** This one is most likely to be found for 92 ZRs.

Any of these should be good for the 91-92 ZRs.
