Hey guys I'm Zakk, after many times of reading threads from my DA almost 3 years ago to now with my 91 Crx Si I finally joined.

so as of right now I'm working on my Rex. I'm doing Ls Vtec. I already have pre much everything. I am confused about few tg8ngs #1 I don't know much about obd0 #2 dunno most of the plugs. Bright side I can do my own wiring with guidance meaning as long as I know where what goes where. I did a swap already previous experience with my DA la vtec/ auto - manual build. I currently have a b18a1 block that will be mated with obvious b16 head. Where my problem lies is with wiring. I'm using a 89 crx DX wiring harness where mine is 91. My block is da so it's obd1 which I love but I need to convert car. Personally would like to avoid jumpers I know their simple just not for me. What I wanted to do was just use my DA engine harness. Will also be using high impedance injectors. I already have diagram for re-pining distributor plugs and re-pining ECU to obd1 plugs. What else would I have to do? Is there any threads already up about 89-91 crx bseries obd1 swaps ? Can anyone help me as I go! Did my DA wanna tackle this. No I don't plan to sell car will eventually go to one of my 2 boys. So will be around a while. Also in market for some parts of there's any sellers
