Bussmann RTMR and relayed headlight harness question

[Tire_Marx]

I am looking at getting a Bussman RTMR or similar to wire some accessories into my 97 suburban. The primary thing I want to wire in would be a relayed headlight setup (Hi and low beams), but there would be a few other thigns that I would be looking at adding in. I want a sealed fuse and relay setup, with as few failure modes as possible, hence the RTMR with associated metri-pak connections.

What I am trying to sort out is how I could do this using a RTMR, as there is no option for a dual-output relay (Something like this: http://www.12voltplanet.co.uk/user/Relay_with_twin_output.png ) that I can find.
I'm not a huge fan of splicing wires when and where I dont have to, so I am looking for some input.

Dual 87 relays are rare birds. You'll surprise me if you find a ready made aftermarket fuse/relay box made to accept and use them. There are stand-alone headlight relay harnesses available that are pre-wired to power dual headlights. You could also run a left and right harness with one relay each.

If you plan on using the RTMR you would have to wire one relay for the high beams, and one relay for the low beams, that would leave you with 3 relays you can use to power other devices. I would use 30 amp relays for both.....remember the RTMR is only rated for 80 amp per buss...so you would have to calculate the draw of each item you plan on using at the same time so you do not overload the RTMR. I found a thread over on Tacoma world which helped me learn about these RTMR's and how to wire them....it changed my world....well it helped a lot in planning my RTMR build.

I actually found his blog that detailed his RTMR build. Fantastic read.
How did you wire the relay to power both lights? That is the crux of my problem, as I can't wrap my head around how to split the one wire into two in a clean and reasonable sealed manner. Again, if possible, I want to avoid splicing and shrink wrapping wires.

I don't think that you can do it with this RTMR. I haven't found any dual 87 output micro relays, I've found the mini's but they would take too much room on the RTMR. To wire the high beams for example, pin 86 would go to the headlight switch, pin 30 would go to the battery, preferably fused, pin 85 would go to ground, pin 87 to one side of the high beam , and the other pin 87 to the other high beam, you would them do the same for the low beams.

You could use something like this RTMR just for relays but you would still have to have separate fuse panel.
