I have started putting together convertible top relay kits. They work on the same basis as a headlight relay kit, removing the load from the stock wiring, relay and switch. Those up/down switches for a convertible top car aren't cheap!
NO CUTTING REQUIRED!
I use a 12 ga, 30 amp fused power line to Tyco/Bosch relays which are secured to the driver side of your pump housing mount bracket. A pair of flat 2 way connectors tap in series into the existing mopar harness. I don't use any low cost relays, ever.
Cost for a kit is $80 plus shipping. US shipping is usually about 10-15. Shipping to Canada would be in the $15-25 range, maybe less depending on box size. International buyers are welcome. Same as with the headlight relay kits, package discount apply to multiple purchases at one time along with prior customer loyalty discounts.
