ok so am trying to make my own conversion harness to run my b16a2 with obd2b distributor the stock distributor (b series distributor plug)

i started my own right this was the diagram i followed


every other wire i matched except for
CKP(CRANK POSITION)+ Blu/Grn(obd1) and Lt.Blu(obd2)

from my obd1 plug i have the Blu/Grn unpluged because my obd2 plug doesnt have a Lt.Blu wire..

here is what i have at the moment

thats my CKP(CRANK POSITION)+ Blu/Grn from my obd1 plug

what i do now..??

From that pic, it looks like you wired the "Speed Output" from the small OBD1 plug to the crank position positive that you're looking for. The Speed output wire should go to that other big hole that is plugged up (next to the black/yellow wire), not where you have it. Check out this image I made and compare:


The wires go in the exact order for both setups; pin 1 to 1, pin 9 to 9, pin 10 to 10.

but out of my obd2b distributor plug a Lt.Blu is suppost to be coming out too
which thats where the Blu/Grn from the obd1 plug attaches too correct

by the way is obd2b for b series distributor

I honestly don't remember what manual I got those colors from, and who knows what manual (or plugs) poison got his wire colors from. It could very well change from car to car (integra vs civic), year to year, engine to engine. I've seen some crazy color differences on different cars, so I wouldn't even go by the color too much. Just match up pin for pin and you'll be fine. I've used that for a few cars now, and it's the same things that this thread says to do (6th post down):

I agree with civicspoon. the blue wire in the plug next to your middle finger is for the speed output(tach wire). the lone wire that doesnt have a buddy goes to the light blue wire on the obd2b plug. the big empty spot on the obd2b plug is where youre tach wire goes to.
