The mising blue wire is the tach.. Just tap your crx blue tach wire with the ignitor wire yel/green, and it will work.

PS, that chart dosent look right to me, lemme know if you want me to post a conversion chart for obd0-2

 

id like to know more obd2 stuff so im down. oh by the way ill be callin ya soon ive got the money i need for the ecu conversion from you, money has been tight an thats y its been like a week since we talked

 

For rywire jumper, or any color to color jumper...

orange to yel
wht to blk
orange/blu to green
wht/blu to red
blu/grn to blu
blu/yel to wht

solo position white to yel/grn

blk/yel to blk yel

blu to blu (tach position, solo)

-----------

If you have no blue tach wire on the obd2 side, you can tap your obd0 tach with the yel/grn.


(rywire)

 

ryan, look at the obd2 plug pic i got. is the blue wire that i have the tach wire since i only have 1 blue? or is it something else?

 

You have no tach wire in the pic, so simply take your obd0 blue tach wire, and tap it to the ignitor wire (yel/green on obd2)

So the yel green will be wired to the solo white, and the blue on your obd0 side.
