Default Code 87 Problem

Hi guys,
I just installed a 91 5.0 and all engine controls into a non-ford car
( an Rx-7 ) .
This is going to be a smog-legal project, so i have to get it right.

The car is running and I got the check engine light working but the fuel pump error code 87 comes up and keeps the cel light on, so I have to clear that.


(code 87 (oc): FP relay circuit failure- suspect inertia switch, fusible
link, FP relay. )

I did not use the ford relay when wiring up the rx-7, I used the stock Mazda set-up.

I'm getting strange reading of 6-7 volts on pin 19 of the ecu even though the wire is cut
.

I think I may get rid of the code by applying 12v to pin 19, but thought I'd run this by you first, as I don't want to blow up the ecu .

Here is a copy of the schematic :

Sorry for the lack of detail on the picture, I can e-mail a better diagram to you if your interested .

Thanks for any help.
