Looking for the location of a splice
1992 F-150 Well I found my vacuum leak with propane,it was the throttle body gasket. But it was still idling to high and sending out a KOER code 412.
Vacuum is steady @ 21". I checked everything and tested all of the sensors and they were ok.
When I checked the voltage at the ISC connector I only got 2.45 volts but it dropped to 0 and the same for the EGR connector. In the electrical schematic at 25-B it shows a splice, the same one the injectors get power from(and they all work). Does anyone know where that splice is located?

I had an engine wiring harness from a v6 ranger, also speed density and it had 2 wires which were each spliced to 3 that went to the injectors.
On that particular one, the splice for the injector wires (3 & 3)was partway into the engine harness.
Totally hidden away inside the harness.
I have no idea why they would do that there, but they did.
Doesn't necessarily apply to yours, but you could have something similar.
