is it acceptable to crimp two wires into one terminal?

I'm going to be wiring up a switch panel composed of 4 switches soon. (3) SPST and (1) DPDT.

there will be 3 wires always hot, and 6 ground wires. I considered using a small busbar, but space is limited behind the dash. If I can make a proper connection, is it acceptable to merge like wires together in order to limit the amount of wires in the bundle?

for the power wires, I would just put 2 tails on each the blade terminals. Probably the same idea for the 3 SPST grounds, and the 3 grounds on the DPDT, then just merge the 2 grounds into 1 main via butt connector.

I'm thinking 18g wire, with 16g for the main power and ground. they will be running of an aux fuse panel mounted where an Spod source would be placed.

Also, does my rough diagram here appear correct? the switches from left to right will be driving lights - fog lights - winch power - winch in/out.



edit: I think the DPDT switch will be configured so that the brown and orange wire should be switched. also found a picture example of what I am referring to:

Yes you can chain two wires in one connector, as long as the combined amperage doesn't exceed that of the feed wire.

Haven't wired that type of switch yet but for reversing polarity, this is what I found. Maybe someone else will jump in who has done it before.

The trick to what you're wanting to do is making sure the gauge of wire used will:

A.) Be sized properly for each load and all loads on the main line side wire feeding all of the daisy chain loads.
B.) Can still be crimped together into a suitable crimp terminal.

I usually solder and heat shrink stuff like that, but that may not be an option for you.

Yes, I absolutely plan to solder and heat shrink. I'm very particular about my wiring.

I've read the LED's in the switch draw roughly 0.2a, so even a liberal estimate of 2 amps on the circuit would be well within specs for a 16g wire.

Agreed. 16 may even be overkill. But better safe than sorry.

^ x2, my frame of thought. I went 8ga to the fused distribution, 14 ga to relays, and 18ga to each LED load. 16 is going to be trouble free.

EDIT -

If you're using relays, I've seen several switch-pod people use a shared ground (12 Volt Guy does it, as do sPod) but they don't share hots wires at all, each of them run a separate hot to the switch and a separate wire back. If you are running off relays, the amp load is very small and you could use even smaller-gauge wire, like 20. But only if you are running off relays.
