hello names mike, new to the site. i have a 92 lx 5.0 hatch back. bought a obd-1 code reader for it but noticed the large diagnostic plug under the hood only has three wires connected to it. there are also two wires coming out by the plug that appear to have been cut. Neither have the groung plug end on them so dont know if one is the ground and one goes to the larger plug. how many wires should there be total? the air conditioning has been removed, not sure if there would have been wires for that that would have gone in the plug or not. the car is also a five speed. just got the car so not sure whats been done to it. just want to get everything straightened out so i can start upgrading it. any information on what color wires go where and how many there should be would be a huge help. Pictures welcome as well. thanks for your help.
