about 2/3 down this link explains how to remove the pins. You can pull some pins from a scrap harness and solder your new wires to them and then plug them right into the ecu harness :thumb:

- Fri May 27, 2011 6:23 pm #257051 ok mine is a 92 lx sedan. i pulled the wires from the computer. and if i was looking at it the right way mine is pre wired for v-tec to the shock tower. :?: if i was looking at it right for example on d there was wires in 1,2,4,and 6. but on 3 and 5 there was no wires. and the wire in slot 6 is like orange with a blue stripe.idk maybe someone before put a diff wireing harness in it? not sure. ok wout it be better to use but connecters at the shok tower to attatch the wires? or should i try to pull the pins from anotehr harness and use pins? i have another harness i could so it with but my friend kinda needs the harness to i need to try to save it if possible

- Fri May 27, 2011 6:58 pm #257058 The orange with blue stripe is for your oil pressure switch I think.... there should be a solid orange or orange with pink stripe I dont remember for sure and that one is for your vtec solenoid.... but why do you need but connectors if its pre wired :headscratch: I would recommend getting the pins from a spare harness if you need any so its a clean factory look :thumb: the easiest way to tell if its pre wired would be to grab the shock tower plug on the car side of it and between the three plugs there should be only one plug with a brown wire delete cap in it

Agin I hope this is some help

- Tue May 31, 2011 8:34 pm #257538 i went to where i bought my ecu he gave me this one. 37820-P06-A51 he insist that it came out if a 95 ex d16z6 . and acording to this site they are right but it doesnt say if its v tec or not http://www.autopart.com/ecc/ECC1992HONDACIVIC.htm he said a p28 either is chipped or came out of a prelude. i called a honda dealer and they said they have no way to tell which computer goes to what motor. help

- Wed Jun 01, 2011 3:34 am #257617 Ok I have 3 p28 ecus at my house rite now 2 manual and one auto all the numbers are the same except for after the p28 number on the tag, the two manuals, one reads A01 and the other reads A02, I'm 100% sure there both manual oem ecus ones virgin and ones chipped , the auto ecu read A52 after the p28 numbers. Hope this helps I'd say the A0 is manual and a A5 is auto this could possibly be referring to a pin placement in the harness or something, I was told before there is a number on them to tell them apart and this is the only number that's different,

To back this up I have a ls ecu and a gsr ecu and a dx ecu that are all three manuals and they all have an A0 designation 8)
