i have a 86honda prelude im dropping a b20b but i ran into a problem. i want to know how i can convert to obd 1 without having to use a different interior harness you know for the lights window (power) brake lights ect. please help anyone:confused:. i was thinkining cutting off the harness plugs from my original harness. and getting a plug from maybe a integra or civic and getting a schematic and just trace and join each wire. please anyone let me know if this could be a option???????????????
 
What do you mean you wish? That adapter is what you would need to do what you are talking about doing. Just without cutting off the ECU plugs.
 
i honestly dont think that the B20b could drop into the 2nd gen lude..... but then again i could be wrong
 
What are you talking about? The link I posted is an adapter that converts the OBD0 plugs to OBD1 plugs with the correct wiring changes so all you have to do is plug in your OBD1 ECU.

I'm pretty sure the B20b doesn't drop in either, but I thought I'd let him figure that out on his own lol :)
 
yes but my plugs from my lude are 1986. the adapter obd0 side or only for 88 and up. so i need to cut my plug and connect a 88 adapter then i can use that adapter
 
It's still OBD0 I'm pretty sure it will work. Just call Rywire and tell them what you are planning to do and see what they can do for you.
