Just need a GOOD quality Jamma Harness for the cab I'm working on.
I'm tired of the crappy Chinese ones offered on eBay or AliExpress.

I read good stuff about suzo happ harness but it happens to be out of stock in the shop I usually buy.

I'd appreciate If anyone could point me in the right direction.
Preferably within the European Union .

Thanks!!

I recently bought this harness for a project cab. I thought the quality was pretty good. English label and 18awg on the power cables and 22 awg for the rest. It's wired for buttons 1-4.

There doesn't seem to be too many good options without having to pay someone for a custom harness.

I have to say I don't think that looks like a particularly good JAMMA harness as it is. It's only $10 though so you can't expect much. The main issue is there is only a single wire connected to the four 5V pins which is going to limit the power you can supply to your PCBs. You could much improve it by adding a couple of extra wires to the 5V pins.

Personally I would roll my own using a decent edge connector (something like a Hirose CR7E-56DA-3.96E) and some decent equipment wire ( I use 24/0.2 for power and 16/0.2 for everything else). It's going to cost you more than $10 in parts but you'll end up with a much more solid harness and you can wire it to suit your requirements exactly.

Thanks for feedback, that wasn't something I was aware could be an issue. I'll likely modify for some extra wires.

Absolutely agree Franco. Assuming you meant AWG, then the above would be the other way around.

I don't use AWG wire. I buy metric wire that is displayed with the stranding, i.e. 16/0.2 is a wire made up from 16 individual 0.2mm diameter strands. A 24/0.2 wire is made up from 24 0.2mm strands.

For reference 16/0.2 is equivalent to 20AWG, 24/0.2 is equivalent to 18AWG.

There is a handy table that can be used to cross reference various gauges [here].
