Anytime. Don’t forget to order the corresponding pins when you order the connector!

Oh, sweet, thanks for those part numbers and the offer. I need to order some stuff from digikey anyway, so I’ll throw these in. I don’t have any more of the radios that I need to mod right away, so I’ll just squirrel the connectors away for the next time.

Good detective work, thanks Eric!

Yeah, I saw the link to it but had hoped that there would be a searchable pdf as that was a really bad scan. I found a supplemental that gave me what I need. *Sometimes* you can take the part number in the service manual and glean the original supply vendor part number from it (Icom is very good about that). That does not look to be the case with Kenwood, though. E40-5737-05 is the corresponding part number for CN1. The part number was a dead end. What I DID find was that apparently, Kenwood sells an option cable for these for about $15 bucks called the KCT-19 and it brings all of the signals for that connector group out of the radio.

I found an old Repeater Builder mail list that describes them as follows:
(All manufactured by JST Connectors, which ironically does the bulk of Icom’s stuff too)
(CN1) ZHR-8
(CN2,CN3) ZHR-3
(CN4) PHR-3

Digikey stocks all of these (even though you just need the ones for CN1 and CN4). If you want, I will make a couple of pigtail sets for you and ship them when I make my next order. I just need to know how long you need the wires to be.

Yep, and it’s linked in the post. Not sure it will have the info you’re looking for, but if you can find it, that’d be cool.

Thanks!

Let me see what I can do. There’s bound to be a service manual floating around somewhere.

I’m sure you could! I needed this right away, so I just did it ugly style, but it would be cool to have something a little neater. The KCT-19 is the kenwood-supplied dongle that plugs in there. I imagine it might be possible to find the connector based on some specification of that…

You know, if you think it might be worthwhile, I can likely match that connector up and make the mod plug and play.
