Does anyone have the wiring diagram for the AC Inverter for a G2 RTL-E? I am installing an inverter in the cab of the truck and was hoping to get a reference voltage to power a relay so that the inverter button in the dash works for both inverters. The new inverter will be wired directly to the battery through a NO relay. I am hoping to find a reference voltage in a spot that I can wire in parallel in a way that won't alter the stock wiring harness and in an area that's easy enough to route to my relay that will be mounted under the passenger side dash. If necessary I can use 2 relays for the 150W and 400W outputs if there is not a single wire that can get the job done. I'm hoping someone has access to a repair manual that shows a wiring diagram for the stock inverter. I pulled the 70A relay on the passenger side under the hood, but the coil is only energized for the 400W mode. Any help/input would be appreciated.

Ok, so it looks like no one had a pinout or wiring diagram for the inverter circuit. I've installed everything and it is working as intended. For others who are looking to do the same sort of setup as myself I will give some useful information. It's easiest to work on wiring in your signal wires by going under the drivers side and pushing the inverter button out of the front, there is a little retainer on the bottom that's easy enough to access. If you look at the wiring on the back of the button you will see 6 different colored wires: Blue, Tan, Red, Gray, Brown and White. Gray appears to be the common (-) most likely for the lights under the button. The wires I needed were the White and Brown wires. The White wire is used in the 150W mode and the Brown wire is used for the 400W mode. What's interesting about this setup is that the wires are switched on the (-) instead of a switched (+). In order for the relay coils to work I used the the large wire that was connected directly to the battery to connect to the 85 pins (for the coil) and the 30 Pins (switched power to inverter). The signal wires from the buttons were connected to the 86 pin of the respective relay (2 relays were used). The 87 Pins were connected to the wire going to the inverter. I routed the main battery cable through the same grommet as the hood release and the 3 wires on the driver side were fished behind the dash to the passenger side. I used an old light fixture bracket to mount the relays and tucked the wiring up and behind the audio amp. The (-) side of the inverter I drilled a hole under the trim piece about 8 inches from the inverter and riveted it in there (I removed some paint with a rotary tool). The rest of the wiring should be easy enough to figure out on your own and the time it takes only adds up to the final fit and finish of how you want it. I used 4-6 AWG Battery Terminal Copper Ring Connectors to the battery, inverter and ground connections. I soldered the signal wires to the relay leads and used heat shrink. I used heat shrink and large (blue) wire nuts for the larger splices. The relays used were 60/80A iRhapsody brand from Amazon . The inverter was a 1000W ordered from Amazon as well. I don't intend on using the inverter for much more than 500W, but I didn't want to use a smaller inverter to its max. The inverter itself comes with 50A fuses (I assume for the DC side). If there are any questions/concerns about this install please hit me up!

So I was wondering if you ever made this happen? I have the backseat yanked in my 2019. I have a 1000w inverter, A DC to DC charger, 2 bus bars and a fuse box. I am currently trying to figure out if I can print a bracket to mount a slim 100ah lifepo4 from litime behind the backseat and fit the dc to dc inverter and 1000w inverter all behind there.

Then run 3 AC outlets.

1 in the console for the backseat with 2-12v and 2 USB-C PD ports. 1 AC at the rear of the truck in the utility box with 2 12v, 2 usb c PD. Power switch for inverter will also be in here. 1 AC in the trunk with one 12v in the trunk.

Edit. So I've been unable to come up with the solution because the thousand watt inverter I bought and the DC to DC charger are both 11 x 8 x 4. I'm building a shelf that I'm going to mount underneath the rear seat and put the battery behind it. I'm going to lose a little storage space but this is all I can think of. I just thought you might have an idea since it sounds like you've done quite a bit of modification a couple years ago.

Any thoughts?? Sorry to revive an old thread.

Just run a bigger cable from battery to rear with a cutoff no more than 18" from battery and install any pure sinewave inverter.
