I have a bare 89 civic hatchback no harness no ecu what do i need to be ready for the swap.. shift linkage, what harness and ecu do i need to run obd1, and someone said something about transmission conversion adapter

You're going to need an engine harness from a '94-'95 Integra GSR and an OBD-1 GSR (P72) manual ECU. The transmission conversion adapter is a mount kit that makes swapping the B-series engine with hydraulic clutch transmission into the 88-91 Civic and CRX a bolt in procedure. It's about $333 from Hasport, but can probably be found elsewhere or used for cheaper. You're going to need B-series shift linkage from any B-series engine. It'll bolt straight up without modification.

Hope this helps!

yes sir it does I have hasport shift linkage and mounts ordered should be here any day.. also how would I go about tucking the harness or should I get it up and running before I worry about that cause like I said motor bay is stripped except what I haven't figured out how to reroute

Personally, I would ensure everything works before you begin tucking the harness. If you start your tuck now, you may never find the problem after the tuck, if there is one.

If you've never tucked a harness before, I'd start reading here: https://honda-tech.com/forums/honda-...ssion-1693934/ If you're not comfortable taking this on yourself, I'd get a premade harness from reputable a shop such as Rywire. For about $500 (for the basic one) you'll have a quality harness that you will not have to worry about.

it seems to be harder to find gsr b16 so will a gsr harness work for a ls b16 or when I find a gsr head later will I have to get the gsr harness then
