Hi, I've done a lot of research and it seems like there is a lot of misinformation!!

First off, I have gotten the D series motor out. I would like to use the GSR motor harness to plug into my stock 93 Civic SI firewall harness.

According to http://www.ff-squad.com/tech/w...5.jpg, I need to wire up the IAB and the evap purge solenoid.

However, according to C-speed's how-to (http://www.c-speedracing.com/h...4.php), only the IAB and the knock sensor needs to be wired up. It mentions something about A20, which I don't understand.

Any insight guys? Did I mention I hate wiring??

the last one i did with a complete harness all i had to do was knock and iab.

so the gsr doesn't have an evap purge solenoid or it's already wired up and good to go?

i wasnt aware they were different, the one i swapped was fine, 92 or 3 cx ( been so long ago i cant remember ) 94 gsr, swapped the whole harness, took the knock and IAB from the gsr harness at the strut tower and ran them to the ecu.

it has to have an evap purge valve.
