ok heres the deal i recently picked up a DB2 harness so i can convert my LS obd0 to obd1 well i pulled everting from the fire wall out and took all the abs wires out since i have no abs and slapped the new hardness in .Now here is my question if some of u can plz hook me up with some pics since i went ahead and put everything in and it looks kinda wierd because on the driver side im missing a plug its actually hard to explain so ill go ahead and take some pics and show u and see if u guys can help me out i would really appreaciate it. passanger side
driver side
this is what im having problems usually the other harness ive seen have a 4 prong adaptor but this one only has 2
and the other thing ive seen is the plug that conects to the engine harness is sopuse to be on the passanger side instead of the driver side . thats why i want to know is this is how the engine bays look on the DB2
No pics but this might help:
The DB2 (B17A1) doesn’t have a Fuel pressure regulator solenoid, (the vacuum hose goes directly to the intake manifold) it (the DB2) has only an EGR solenoid. That is why it only has a 2 pin connector…the B18A1 has a 4 pin connector (what you have). You have a few options to make this work. Switch to the DB2 solenoid pin connector and hook up the press regulator hose directly to the manifold and see how the engine runs. Or go back and rewire the two extra wires for the missing solenoid to wherever they are supposed to go…
The plug that you are talking about that is on the drivers side is the accessory plug (RPM signal, Alternator light signal, etc.). On Obd0 it’s on the passenger side, DB2 they switched it to the driver’s side. If you have the engine harness for the DB2 it should all connect together. If you are using an OBD0 engine harness…you will have to reroute your acc wires from the passenger side to the drivers side (not a lot of fun).
Hope this helps…

im using OB1 harness that i picked up from and RS thats why i was asking cus the wires for the engine are in the opposite side but yeahill have to go back and get the other sensor hopefullly i can buy the harness to and just make my ls to ls-v or get a gsr on
The easy way will be to get a DB2 engine harness. You can modify your OBD0 harness to make it work (a lot of work). With some depinning, you just need the 2 pin connector from a DB2 to make the solenoid connection work. By the way, what ECU will you be using?

Wait youre using a DB2 B17a1 engine harness for an LS OBD-0 chassis? Why not just use a OBD-0 harness then convert to OBD-1 instead of using a DB2 harness?
It sounds like he aquired a DB2 main (chasis) harness and installed it on a OBD0 chasis. He now either needs a DB2 engine harness or convert his OBD0 engine harness and modify the solenoid connection.

yeah i got the obd1 gsr main chasi harnes and ill be using obd1 engine harness from a 93 rs i have laying im prety much getting rid of the obd0 harness period .so it will be a 90 integra obd1 instead of obd0 and ill be usimg a p75 or pr4 ecu if i leave the ls motor on if i decide to go vtec b18c1 or b16 then ill use a p28 .my problem was the engine harnes from the 93 rs wasnt matching at all to the db2 harness the plugs on the RS are in the oposite side than the db2 and that egr plug is different from the ls instead of 4 wires it has 2 so ill be doing another trip to the junk yard and getting the rest of the parts from the gsr teg
There is a gsr teg at the junkyard? Does it still have the trani?

yeah went back is still there and picked up the selenoid i need it …no tranny
