CBR Forum - Enthusiast forums for Honda CBR Owners - Point in the right direction 94 cbr1000f

Hey guys. I need a little help. I picked up a crashed 94 cbe1000f for $300. Mainly for the engine. It had 2 pickups on it but only one one wired and I can only find a yellow and I think yellow and white wire on the harness. The other one has a blue wire and I can't remember the other right off. I had to order the hear that it detects because the one on it was not right. Someone just stuck one on it from something else. My question is does it need both or just the one? I can't any pictures or good diagrams showing me. Can someone point me in the right direction or help out. Thanks.
