I know, I know search... but I didn't turn up any 99 pinouts under the topic "99 civic Si pinouts" Please assist. I am making a jumper for my 98, but i am using a 99 dash and engine harness... I already have the clippings for the obd1 ecu and the block off a 99 ecu to make it, so telling me to buy a jumper is wortless. I have marked down all the pinouts color/placement in diagrams. I know that honda utilizes the same color for certain wires i.e YEL, BLUE, RED, and BROWN for the injectors ect but i want to be certain i have everthing pinned out before i strat heat srinking and soldering... THANKS A MILLION for a link or assistance.... Here is what i have compiled thus far...

CHRIS who ever you are your the ****!!! Thanks foo..

thanks deepSI. I used a manual and the colors just didn't match for those pinouts. I didn't want to wire it up wrong. I need to double check the function of some pinouts on connector 32P.

#4...LTGRN/WHT....VSV (drives evap ctrl canister)
#6...RED/YEL....PCS (evap purge)
#8...BLK/WHT....SO2SHTC (2ndary O2 sensor heated)
#10...BRN....SCS (detects service check signals)
#16...GRN/YEL... ???
#17...BLK....ACC (A/C clutch relay)
#21...BLU/YEL...KLINE (sends/rec. scan tool signal)
#29...LT GRN/GRN....PTANK (detects fuel tank press.)

 

what did you need help on???

 

I got all but 2 of the wires soldered up. We plugged it in my boys gsr powered SI and it fired up, but it idled like **** and the tach wasn't working. I traced the wires (one of the two was the service connector wire and the other the icm/tach signal). I got a help from a local who knows his honda ecu's forwards and backwards. Once connected the car ran strong but no vtec... (the wire was properly soldered).

NOW IT WORKS FINE AND I PAYED ABOUT $45 BUCKS FOR MY 0BD2B TO OBD1 JUMPER. DIY.... I LOVE IT

THANKS GUYS FOR YOUR HELP AND A BIG SHOUT TO JOESPH WITH THE CONVERSION CHART THAT HELPED ME TROUBLESHOOT...If I had only had it from the start... lol

I will post the wiring conversion soon...
