So here i am, purchasing a helms manual for my 91 integra LS. I decided that since ls/vtec was near i would buy the 93 manual so it would include the b17a vtec specs. Well my largest question is, are the pinouts for the LS different between the 90-91 and the 93? I have wiring diagrams on how to hook up the PR3 SIR1 ECU to mine, the PR4 LS ecu however the pinouts for my ecu don't match what the helms manual says. Also i looked at one pinout diagram and it said 90-91 integra, the other said 90-93, so im completely stumped. Almost all of the pinouts given do not match the helms. For instance A1 A3 A5 A7 are all injectors according to the conversion diagram, in the helms its A1, A2, A3, A5 Can anyone shed some light? Has anyone done a swap using this ECU into their LS. Any and all help is greatly appreciated.

Well 90-91 is non-OBD, and 92-93 is OBD I so that is probably the problem right there.

Damit i had that feeling in the back of my head, what the hell was i thinking when i bought this damn manual, F$@k. I'm okay now it should only effect the pinouts for my ecu, thats about it. Thanks for giving me that slap in the face, appreciate that one. If anyone has info on the swap, im still interested, and thanks again reid.

hmm so now that i got this info, how did ANYONE go about ADDING a wire to the ecu pinout? Its going to be a pain especially since there is no wire there already, how am i going to do this? I bet i could go buy some metal clips that would plug into the blank in the harness couldn't i? anyone?
