Whelen WeCan repurpose?

Okay, had a thought, but I'm not knowledgeable enough to know if I'm crazy (opr rather, crazier than normal).

I'm still in the process of outfitting my F150. While I'm planning on utilizing a Unitrol 330, because I'm familiar with their operation and I had one in my first build (I'm nostalgic) pictures included - this one from Greystone's thread - for those who have no idea what I'm talking about:

I know they're unsupported (<angry>It's only been 30 years!!!</angry>), so I started looking at other options. I was thinking about a CenCom variant, but I'm trying to have a lower profile in my truck than a full panel.

Along the way I found the Whelen WCC9 controller online :

I like it, but I saw it's intended for use with a WeCan system (like those found in the Justice and Freedom bars). If I could use them on a CenCom Gold I'd have bought one already.

Recently I've also seen a ton of the WeCan Control Points for sale for pretty fair prices:

I know the control points are designed to fit into various light bars and perform certain tasks.

My question is - has anyone seen the control modules repurposed for non-lightbar applications? Is it possible?

Does anyone have a link to a wiring / pinout diagram? I haven't been able to find one (although I'm on duty so my search has been brief).

Thanks folks.

Basically, you want to use the WeCan control point as a flasher?
Nope, unless it has that option. If I needed a flasher and light control I thought my only option is the Carbide, but I'm happy to be proven wrong. I'm looking for a control that will allow me to select the following:

Level 1 - perimeter lights (corner or rear bumpers and fog light nacelles)
Level 2 - rear cap lights and rear facing bar
Level 3 - grille and dash lights and HL flashers (on park switch)

The kicker is that I also need to have two color controls, one for blue (fire/EMS) and one for amber (construction).

I modified the 330 to have two split switches - the first will activate relays (the only way I can figure out to do it) to allow blue, amber or both. The second switch activates left or right arrow function for the TA feature in the rear bar (both is center-out), but I'm still assembling components and want to get enough to make a test board and verify function before I install it and find out it's FUBAR.

If I could use the WCC9 with a CenCom Gold or Sapphire I wouldn't mind (even though I have a separate siren already), but I believe it's incompatible.

A Whelen smart logic flasher might suit your needs.
This probably isn't kosher to the community but I use to have my whole car run off a Whelen liberty IO board installed in a project box. Gave me the wecan functionality I wanted and it plugged right into my cencom but you could also plug it into the wecan control point. This was before smartlogic and carbide was available and before you could find cantrols for sale on ebay

You know, that just might work, and probably for less hassle than mucking around trying to adapt a WeCan box. I'm not above DIY (as seen by my 330 project) but my wife has helped me acknowledge that my time is worth money. (I always thought I'd have more free time after I retired)

8 inputs means I could select one for each color and warning level. Now I wonder if the WCC9 would interface (it will probably have to be a one-off)...

The WCC9 (and Control Point) exchange very lightbar-specific messages over "CANbus" (the blue/green wire-pair). I just don't see how this connects to a smart-logic flasher.

Dammit.... I was afraid you (or someone else) were going to say that. I'm so used to the slide switch. I looked into the Brookings/SoS 99x series programmable switch panels, but it's only got 6 outputs, so I'd have to have another box to use my TA.

Sorry! but I didn't want to see you throw $$ out the window. I gotta say though, I dig @FusionWolfs not-so-kosher repurposing of the Liberty I/O controller. That was cool!

No, no, I appreciate it. The ability to use the WCC9 is the reason I'd think about following his example, but with no clue as to what the control points can do, It'd be a lot of playing around. The tinkerer in me wouldn't mind it, but I don't have the ability to dedicate a week to diagramming the pinouts and various options.

Another option you might consider: an MPCxx controller connected to a BH8140 high-current switch. The MPC has a modest footprint, is programmable, and the BH8140 with 8 outputs, might be enough to drive your level1/2/3 blue/amber goal. I'm sure I'm not alone here in being willing to do the MPC programming for you if you wanted to avoid the Windows/PC/RS485 hell that sometimes occurs...and you'd have only two wires between the MPC and the BL8140.

What about using a liberty sc I/O board and running off the mpc, I had a thought about that myself.

I appreciate the offer. While I was familiar with the CenCon stuff (even downloaded the software), I didn't know the MPC existed.

I just looked at it, and it looks like it has a surprising number of functions in such a small size. Unfortunately, it also appears to be roughly the same size as a CenCom head, so it might be a bit big for my current thoughts (it's the same reason I considered and discarded the PCC series, Z3 and FS SS) . If this was 25 years ago, I'd outfit my POV like a duty rig in a heartbeat, but I've BTDT; now I want to be able to do the job without it impeding my day to day existence - like being able to fit 3 in my truck ;) - and in today's climate, leaving a vehicle that screams "OFFICIAL VEHICLE!" unattended may not be the wisest thing.

How about https://www.strobesnmore.com/whelens-all-new-8-position-key-pad-with-remote-relay-module.html ? Doesn't have slide switch but otherwise -- same footprint, no wecan, eight outputs!
I've thought about it (and the SoS SW830), maybe wired as
Amb1 Amb2 Amb3 TAL
Blue1 Blue2 Blue3 TAR

I may wind up going that route...I'm just addicted to my slide switch. I thought about the FedSig 6 switch, but it's like the WCC in that it's designed to work with specific bars.
