b16a2 swap in 90 4d dx
 

im putting an a2 swap in my civic but im have a hard time trying to figuer out how to modify the engine harness so it can function properly with vtec, second o2 senseor (im gonna be running a dc header it has only one sensor with a 4 wire plug). i know i need to convert over to mpfi and i know how to convert over to obd1 injectors.

ive looked on this ( http://www.angelfire.com/d20/hcivic88/4gtech.html) the past couple of days and ive also been on yahoo, google, and h-t search to see if i can find diagram of a modified engine harness or anything that can move me in the right direction but still no luck!!

if any body can help id appreciate it!!

almost all of your questions can be answered in the faq....

but take your harness, convert it to mpfi, then you will need a obd0-obd1 jumper harness, as well as 4 wire 02, the obd1 dist to go with your engine, and pigtails to correspond with your injectors and dist....the jumper harness will have the extra wire for vtec etc...

if all this seems overwhelming contact rywire, im sure they can build you a harness that will be headache free ready to plug in...
