wats up guys i have a 98 civic ex.just did a 96 ls swap,but im having a problem with the wiring. mostly every thing pluged in exept my crank sensor. the plug out of my ex harness has 3pin wire and my crank sensor has two,what can i do.is there a web site were i can find a wiring diagram

 

Are you talking about the "Crankshaft Speed Fluctuation Sensor", a 3wire on the civic engine and a 2 wire on the LS engine

98Civic...

White to white/red-------- CKFM pin on PCM , [ECU/ECM/PCM]
Light blue to blue/orange--CKFP pin on PCM
Black to brown/black------- chassis ground

96LS...

White to red/white---------CKFM pin on ECM [ECU/ECM/PCM]
Blue to blue/red------------CKFP pin on ECM

So looks like the only diff. is the LS engines CSFS does not have the chassis ground and a diff. in color of the CKFP lead and the Civics computer is called a "Powertrain Control Module" and the Integra computer is called an "Engine Control Module". 94

 

so just cut the plug of and butt conect the wires to the ls plug and just ground the black one.or can i just feed the black wire back into the harness.sorry im not that smart when it comes to wiring.and is there annything else i should know about this wiring

 

Connect the two that are needed and see what happens, the ground is just a ground, the diff. may be that the LS sensor grounds through chassis and the Civic did not. 94
