Make sure the wiring is capable of handlingcurrent. 10 or 12 gage.

I removed the original switch (momentaryone only) and took it to NAPA and purchaseda center off, momentary each way made by the

same manufacturer whose name escapes me now.

(eRS) /1111& 67 0../l-nI'1"YOHcan-th.6n veF¥~tbll)Lpfy..Dffthe old top with:1CC printed on it andswap it out with the new switch. Works ok.

I put the relays in the bottom of thehousing where the Jack Pad controller/Tr.anscontroller are located and put thefuse where I can get to it under the dash.

" Y.oucan locate the relays where ever you want.

Follow the instructions, they do work.
