hey honda-tech i have a 1991 honda crx dx which was auto now converted to manual. i want to convert to obd1 with a chipped p28. do i need to have a custom made jumper to work or can i still use a manual jumper harness made by rywire? is there any difference? any info will be appreciated

 

i dont think theres a difference in the ecu plugs i did an auto to manual swap and just changed the ecu to a manual one and it ran fine.

 

do u have to change any the motor mounts? from auto to stick?

 

u need a ob0 to obd 1 jumper for the ecu u also gotta change the distibutor an u need the jumper for that as well and a 4 wire 02 that u can wire urself to the jumper
