ok so i got a pretty good deal on this motor but i'm a little confused as far as the wiring goes. the bottom end is a 99 b20b and ctr head but w/ b16a1 intake (obd1) so there is not spot for IAT 2 bolt port that looks like a fuel pressure regulator could go there. So anyway my question is could i run my stock harness btw its a single cam 2000 ek hatch dx non vtec. i know i would assume i would need to def get jumper harness for obd1 head and other stuff but can run obd2 dist. td84 to be exact. thats what was in the car but owner cut harness and made it obd1. i want to be as reliable as possible and with as little amount of wiring. I'm wondering if i can use the obd1 intake mani and as far as the iat sensor use the factory one in the inake tube itself on new motor but my questions are what would i do for the other connectors that arent there. i know obd2 need knock/ckps sensor so by doing p28 obd2 to obd1 jumper and custom map i should run fine and then worst case just have to run like the 3 wires straight through firewall for vtec? any help would greatly be appreciated. thanks. feel free to pm and i can give my cell to anyone would rather explain over phone vs typing a book lol....

 

You need a 0db1 ex harness with a p28 and it's plug and play, you will need a 0db1 alternator tho

 

will the harness have on obd1 harness work for obd2 bottom end?? remember its a 99 b20b with a 90 ctr head ob1 w/ b16a1 intake mani....

 

Use Your harness
P28 with obd2b to obd1 ecu adapter
Obd2b to obd1/2a distributor adapter
3-2 wire IACV conversion
Wire VTEC solenoid and pressure switch
Place the IAT in your intake arm

No need for knock or CKF wiring as the p28 won't look for it.

 

ok cool...i'll check it out. thanks guys. this is my daily i'm trying to get all the parts and do this swap within a day or two max. just wanna have it reliable lol.

 

also will my fuel rail and injectors work for the other motor? someone told me yes other said no i need more fuel....i'm not trying to go all out even after basemap p28 for phearable or rywire i was getting a wideband anyway but just wanted someones opinion. thanks
