Hi All

I am trying to wire in a car stereo in my mk 4 focus st edition (2021). We have got it all working but we were having an issue with the front door speakers.

 

When connected to a class d kenwood amplifier (using high level i.e. converting the signal that was output from the b&o amp) my amplifier would go into protection mode. This meant it wasn't happy with the speaker. Rears and sub no problems.

We found out that there was variable resistance running down the factory wire. When the ignition was on it went up and down between 1.5ohms and 8!!

 

Oddly, this didn't make any difference to the stock system or even the speakers I replaced in the door until we tried using my kenwood amplifier.

 

We think there is something else plumbed into the stock speaker loom? We replaced it and it solved the problem but now we have a ecall error?

 

Wondering if ecall is "monitoring" the front speakers? If so it would be good to understand where it connects to them? Can anyone help me locate where it may be connecting? It's either this or ANC microphones? It's odd the the resistance changes?? Not heard it mentioned anywhere else.

 

I hope someone can help.

If this a 2013 model should it not be a Mk3 Focus ?

I see. Sorry. New car 😁. I've updated my profile now

Does Ford Microcat allows to find proper terminal pins? If so, can someone please check these for Focus MK4. All are 22 Gauge. I did retrofit camera already, but have to redo due to inaccurate pins used.

• C4357 Female pins - this is rear camera connector. I do have pigtail, although there are no spare pins, and if I fail to crimp it, I will no longer able to redo.

• C405 Female + Male - this is PDC (Parking distance connector) where C4357 ping are eventually connected to.

• C2280F Female - BCM connector. This is where PDC need to be connected with.

• ACM module Female - Audio control module (SYNC) for trims without APIM. I don't have connector name but the photo (square connector at the right). 

Hello everyone.

Sorry I don't have the pinout of the connectors but I think that @Walkie1973 might be able to help.

MK4 connectors, open index.html in a browser. C519 is missing, is there such a connector?

Not exactly, the PCM for the Mk4 is C519, but I think the OP wants to know what the full connections of the Mk4 PCM (ECU) pin out to. 

Which obviously will be numerous connections.

Hi  @Walkie1973

have you pin out of C210 and C2280F?

thanks!
