so ive got a 93 hatch, recently put an rb25det in it.
heres the problem, i purchased the wiring specialties swap harness, i hooked everything up according to their instructions on the wiring specialites site.
i hooked a plug up wrong and everytime i hooked up b+ the starter would turn over. so that was wrong, so i switched up the wiring and hooked in the starter solenoid
so the motor is not cranking over at all, i get reverse lights high beams( no low beams ) and just about everything else that gets power has it, ( not hearing the FP prime at all ) so when i was testing power with my test light i get power at one of the plugs when i turn the key to try and crank it i get power at that plug, but when i move the test light to the starter solenoid plug ( the spade terminal on the starter ) i dont get any power. any help would be awesome !

have you checked your relays or fuses see if you burned one out?

I did the same recently with the wiring specialties harness, the instructions are pretty good, but I remember the whole starter part was a little confusing.
Make sure it is hooked up exactly as it says in the instructions. With the alternator, battery, and harness power using the starter deal as a common terminal for the three . Also check what rb25guy said, if you verify that you have everything hooked up properly, then it will be something along the lines of what he said.
Might make sure things are well grounded too

I've checked fuses and relays but my harness is an auto harness and I'm swapping so when I got the trans harness it came with the auto manual conversion harness and there are a few plugs where I've got no idea where they go

Just follow the instructions dude . It has pictures and shit
The auto to manual conversion harness thing plugs into the first two plugs at the back of the fuse box, while the third plug plugs into the plug on the side of the fuse box, if I remember correctly.
For the one on the side, sometimes it's necessary to swap the plug from the old harness as some of them have different styles. Some have 4-pin, some have like 7 pin. This is only on some of them though, you have to see.

Then why wouldn't the rep at wiring specialties tell me that?

Maybe your car is different dude, and he saw or whatever, I dunno.
I recommend just doing it the way you're supposed to
All the instructions are on the website, If you had read them, you wouldn't be slinging accusations like a little bitch. Just trying to help man.

Quite friendly aren't you, and oh so helpful. I have read the instructions and have gone over and over them. There are plugs that are different on my harness that don't match up to the harness I ordered specifically for my harness. And what accusations have I thrown around. I've been emailing yury back and fourth?

The instructions do list what to do if your plug is different:picardfp::picardfp:
Unless you have the one set of plugs that are different than all 240's in known existence.
Whatever dude, just figure it out or wait for someone else to help u

Check the 2 plugs that are by the battery tray.. 1 brown 1 grey.
Make sure all the colored wires line up in the plug. I personally had to re pin 2 wires. And have also know another person that had the same issue.
WS just tells people to direct connect the starter for some reason...

went through with a multimeter. volatage might be a little low due to a low battery but still no power to the starter terminal.
