Hey Guys,
Check out my 18M slat mod:

I don't like how Cobra does it with the mini cue connectors so I cut in a DB25 connector and wired it in myself.

Found some DB25 angle adapters online / here's a pic with the adapter installed / cover still closes with the angle connector

Here's a pic with the cable connected

Found these slats online for $41 each and the can be wired series or parallel

What do you think?

That impressive. Can you still use pins 13 to 18 and the cable at the same time?

I did a similar mod to put the connector on the side of the case. So it looks like this:

Do you have any pics or tips on how to mount a db25 connector in the 18M?

I've actually grown to like the boots better than the cases and would like to have a db25 connector on the 18M. The cases are bulky once you start dealing with more than a couple mods.

I'm not a fan of the normal slat adapter, but if I only use those mods with slats, I might be able to deal with them.

I posted pics and tips of my side connector modification at http://pyro.duesman.net/firing_system/cobra-slat-adapter

Yes, all cue still work.

I didn't take any pictures while I did the mod I can share. What I did is, I took a computer DB25 expansion card slot and cut it just long enough to hold the connector. Then I took the 18R2 apart and used the cut off card slot as a template to mark the hole to cut out. Then I used a coping saw to cut the hole. After you cut the hole use the cut off card slot for a backer plate for extra reinforcement. I got the expansion card slots and hex nut screws on ebay.

P.S: I like your set up too!
