There is no grounding requirement for ignition switch. Just plug in the harness. Don't even need key part of switch assembly. You can manipulate switch by turning it with a screwdriver.

Do you have all schematics you need?

well i finally figured it out. my ecu is not actuating my main relay. so today i took the p61 out of my teg and put the p28 in. no main clicking. put the p61 in my hatch and main works fine. so i picked up a chipped p28 to put in. so tomorrow i hope i have good news for all you that have helped. especially dual-500.

Thank you sir and good luck with it. Be sure and post results. :)

A word about the forums - there are many that have tons of Honda experience, some have posted on this thread. Usually, when one or two members have something "under control" the others will stand by and just read thread. You are a new member and none of us know your experience level or overall skill level or what tools you have access to or experience with. So, I (and most if not all the other regulars) usually don't jump in and start off at advanced level stuff. Kinda work that way by seeing the questions and actions of the OP.

ya i spent a LONG time sitting in the passenger seat of my older brothers hondas. got my first ef at 15 it was a nice 90 si hatch stock as a rock. except exhaust, sounded great. eventually got a mini me then a b swap. then it found a ditch at 90 backwards. only surviving parts were diver door, engine, and front seats.

Great! That's when the satisfaction begins to kick in! The wires you swapped would be from one of the Hall Effect sensors in the dizzy. They need correct polarity of the signal to ECU to function. I've got one in the shop that's doing together soon and get dropped back into my 91 hatch when fall weather gets here. A 1994 DOHC ZC with 10.5:1 compression that's been balanced and ported.

Keep your progress posted - I'll post up mine when I start the short block build.
