i just bout bought a 89' hatch with an OBD0 PR4 ECU and it was all for a D17

the first pic the wires are off i think it was the middle ECU plug and i have no idea what that plug is used for, the colors are white/red and red/yellow

second pic the plug on the left has just a plain white wire and the plug on the right has a plain orange and a plain whte wire and they are all crimped to a brown with a black line an had silver squares

third pic is just random wires that dont go to anything but they are a red/dark green and brown/black

forth pic is what looks to be bypassed for something but i havent got a clue what for theres 3 yellow/red squares and 2 red/black squares

fith is a light blue/green and gray/black and pluged in to the the smaller plug is white/dark blue and dark green/red

 

the first pic is with two wires that were in the wrap that wen to absolutly nothing, they are red/black with silver squares and black with silver squares

the second pic is the plug wires are exatly the same as the ones to nothing, which they are 2 green with silver squares and 2 black with silver squares

 

any help??

 

still no help in all of honda-tech and not one person konws anything??

 

Well the first pic, c1 and c2 are the Cylinder Position Sensor that goes to the distributor they connect to blu/yel blu/grn for converting to MPFI.
