OK I'm trying to get my k swap running and I'm having a good old time with the wiring lol

It all started when I got everything wired up for my k swap and was about to start it, k pro showed that it wasn't sensing the ignition on the car being on.

I then found out that I have no power on my conversion harness from where I tapped in to the original ecu plugs at a13. Once I found that out, I started poking around and realized I'm not getting any switched power in the "on" position at the blk/yellow wires at the main relay? Also pin 2 on the main relay isn't getting a good ground. Can I just ground the two black wires at the original ecu A plug to get continuity at pin 2 ground on main relay?

I'm having trouble tracing where I'm losing switched power when in the "on" position (blk/yel) any help?

Btw all fuses are good and I have 3 engine grounds, battery ground, and k engine harness grounded to valve cover grommet

 

I just rewired a CRX to OBD2 and I had to change some things on the main relay. First thing I should warn you is that these cars have lots of variations between models and years. Second thing is not to trust the factory wiring diagrams. For instance, on the TBI engines, the fuel pump is branched off the fuel injector output. Cute. I had to open up the loom near the hood release handle and change the wiring to match the Helms diagram. Set the project back quite a bit figuring that out.

To answer your question directly I'd have to refer to my notes at home. I know that there are two pins with yel/blk wires, the corner pin is the fuel injector output at the driver's side strut tower that also goes to two pins on the ECU. On OBD2 harnesses these don't go to the ECU. The other pin with yel/blk is the fuel pump output. The green/blk is the ECU ground signal. The black wire goes to the ECU on OBD0 but also connects to other grounds, I think it goes to the strut tower as well but will have to review my notes. I can't remember if I had to ground that wire and what I had to do with the yel/blk's if anything.

 

Nobody has any ideas? Are there any grounds in the cabin harness under the dash?*

Also the oem grounds for these as far as I can tell travel through the drivers side shock tower plug and ground themselves in the thermostat housing on the original d series setup. If I'm doing a kswap and pulling the drivers side shock tower plug into the cabin and connecting it to my conversion harness, what is completing the circuit? As far as I can tell these grounds aren't grounded and that may be why I'm not getting power to my main relay and ecu plugs. ...

Someone please help this is my first k swap and need some help from the EF OG's!

 

OK so a little more testing and I found out that I do have power to the main relay at constant yel/wht and at "on" position blk/yel. I still do not have ground at pin 2 at the main relay or power at stock ecu plug a13.

The only thing that makes sense is that I'm not getting ground at the stock g101 which is supposed to be located on the thermostat housing on a stock setup.

I have also run a ground from the main relay to chassis and every time I turn the ignition to the "on" position it blows fuse 14.

Has anyone had this problem before? I've read everything I can about crx k swaps and this was never mentioned. My next step is gonna be to pull the wire tuck out of the fender rail and check the grounds there, otherwise I have no clue how to fix this. PLEASE HELP!
