Hello, I have an 89 Civic Hatch I’m going MPFI on.

I've done this 2 times with previous chassis using OBD1 Injectors, although this time I’m using OBD0 Injectors with a Resistor Box, I’m running a P06 ECU and TD-41U Distributor on a D15B2.

Here’s my question, I have my Resistor Box running off of A15 & A13 YEL/BLK wires soldered to a single wire, when I put my car in IG2 the main relay clicks very fast

i have searched the forums and what I could come up to as a result would either be, Bad Ground, ECU signal Interruption or possibly i wasn’t supposed to use A13? (Thinking it’s this)

I could use some second opinion on this issue,
If this doesn’t belong here I apologize
THANK YOU for any advice.

 

My car is a 90 Sedan, so YMMV, but I ran my +12V to the resistor box from pin #1 in the picture, from the driver's side 14-pin round connector on the shock tower. For DPFI, this is the +12V for the top injector.
