ok, so this is not a kit, but an overview of how to re-wire for your pumps to get full current while still maintaining the primary pump controller functionality.
With this setup there are no DTCs triggered. The Secondary pump gets triggered by the ECU as usual.
You will need 2 relays, separate 20A fuses (one for each pump circuit), and perhaps a bigger 50A for the new power source. A generic hardwire kit will get you most of the components
A couple veterans have used this (socalaviator?) with success. I've helped quite a few people on the old board run this setup. None reported any errors, so if you used this before and have feedback, do post it here!
You don't need to get the power source the same way I did as I already had a 4 gauge wire coming from the battery for an upgraded subwoofer, and from there used a an previously installed power distribution block to run 10 gauge to the pumps. There's better pre-fused power brackets that can do this nicely though.
My 10 gauge may be overkill as well for you (that's what I had on hand), so you should figure you what gauge you want to run based on the current requirements of your pumps.
The secondary pump relay can be installed right next to the original one in the trunk , right side pocket where a dual relay bracket (with the one relay on it) is installed.
I've attached two documents. One if the OE wiring diagram for the ECU, the 2nd is the modifications I've made to my wiring. It involved cutting 1 wire, mainly the power feed INTO the Primary pump controller, and using it to drive a relay instead. From there, the bigger gauge wire takes over.
If anyone has questions on the inner working and can't figure it out by looking at the modification diagram, do ask! But the answer is no, I don't have a kit to do this, I just put it together with whatever I had. Some vendors may be coming out with a kit following this recipe, but I have no insights into what that entails.
