I bought a 89 crx from a friend a little over a month ago. From day one it had a dead cylinder narrowed the issue down to the injector. Yesterday i tried to start it and the entire electrical system shut down. It doesn't matter if i put a fresh battery in or if i jump start it. The dude i got it from did some really bad wiring inside and out if i were to get new harnesses for the interior and engine bay what harnesses should i use and what wiring differences will i be facing. I ran full compression and leak down tests so i know none of the internals are damaged. But would really rather start with fresh wiring and since im going that route would like the most advantageous setup.
