Hi. Been doing my EF I6 and auto into XF ute conversion. All in and bolted up ect.

Here is the problem. Using complete EF loom(engine,instruments,dash) and cluster with a J3 chip with a*** bypass, still using XF steering column and lock, should be easy you say! Not!

For some reason the engine is cranking on the ignition wire(the red/green) and not the start wire(smart lock wire (red/blue)) this wire simply makes the fuel pump relay and another(not sure which one) go beserk. I have tried this with the bcm connected or with the smartlock wire bridged, same diff just no smartlock light.

If this were simply a smartlock problem I would not expect the engine to crank.

I am wondering if there is a short in behind the fuses where the looms all come together.

Any ideas. I can't understand why these two wires almost seem as if they are reversed. They are not. The only wires I have cut and shut, I have checked, all good.

The conversion has gone well but this is giving me the sh....... I mean irrits.

Any help much apprieciated.

Any ideas?

why not use the XG barrel?

I'd be checking earths, I found that XF wiring has a lot of earth near the headlights.

What looms are you running?

Hi. Using full EF engine, dash and instrument loom with EF instrument cluster.

I'd pull the starter relay out and just check to see if it has gone n/c.

Check voltages to that relay while your at it, if its 9~ish volts that may indicate a cross line or feedback.

I'd be undoing the gearbox plug (auto or manual) as well to minimize non thought of places.

I found with our EF to XF there was a difference between XF T5 gearbox loom and an EF one.
strangely enough, I had a similar starting issue with ours. yet I ran a complete XG loom.

then recheck the ignition barrel backing perhaps?

Checked just about everything.EEC relay good. Starter relay good.
Mine is an auto.
Does the same thing at the plug, no switch.
Ideas?
