S550 Connector List

[slonison]

I put this guide together for people who are getting deep into the electrical aspect of the cars.

S197 S550 Mustang Connectors

I, for one, do not like splicing into my car's electrical system. So, I started a project where, anytime I want to divert a signal, be it power or data, I would make an interconnect harness. Basically, a harness where you unplug two connectors in your car and fit yours between.

In order to do this, it is far FAR cheaper to source the terminals and connectors and pin them yourself, than to buy pigtails.

For Example:

WPT-934 (the grey connector on the top) is current $67 on Amazon

That same connector is $1.37 on Digikey

The terminals are $10 for 100+ and the tool to crimp them is $15.

You could buy spools of wire for cheap and still come out for far FAR less.

Kinda depends on how you value your time I suppose

I wholeheartedly agree. I think the same thoughts when I see people doing their own oil changes.

Thank you for putting this together @slonison

No problem. I decided to put them together in one document because often times the style of the connectors are similar. So if the connector is not the same as the s197, you can at least find out whether it's yazaki, Molex, tyco, etc

Hey guys,

Updated the formatting since I wasn't happy with how it looked before. Added in wire colors to make it easier to identify the wire you are looking for.

I think I can add some connectors to your list. I’ve been working on adding an OEM rear fog light to my 2018 Mustang, and I’m currently in the middle of adding heated and cooled seats to my Recaro car the proper way, including adding wires, terminals, MS-CAN, etc. Because of that, I’ve done quite a bit of terminal research myself.

One heads-up: I like that you included extra information such as wire colors, pinouts and functions. However, for example, C340 and C339 are both main seat connectors (Not yet in your list). They use the same connector housings and terminals, but they have different pinouts, functions and wire colors. So if the document is organized strictly per C-connector number, it could lead to duplicate or potentially confusing information, since both connectors share the same physical parts but differ electrically. C405 connector is used in the rear bumper, but that same connector WPT-1544 is used in like 6 other connections on the s550.

Also, pinouts can vary depending on LHD vs RHD and by market (US, EU, China, Australia, etc.). In my case, I’m working on a US-spec car in Europe, and for some retrofits I actually need to reference “China-only” wiring configurations to comply with EU regulations.


Would you prefer that I just add this information directly into the document, or would you like me to send you the details first?

I hear you. To be honest, I only started compiling this as a method of sourcing the connectors via retailers. I hate HATE splicing wires. I much prefer to slide in a plug and play harness in between where there is a male and female connector available. I don't own a 6th gen actually. But I used this to retrofit a plug and play setup for a 2022 steering wheel in my 2013. Making my own steering wheel and multifunction harnesses in the meantime.

If you have a document to share. I would be happy to pull from it and credit you.
