I suspect that using fuse 28 instead of 27 is your problem. In my manual 28 is listed as "Empty" and does not show up on the schematics. If it is on the opposite side of the Inadvertant Load Control Rely from fuse 27 you will get a ground loop through the original lighting circuit when the relay opens. Connecting the power tap to fuse 27 may solve the problem.red one : JRinKY
I soldered all the connection and covered with shrink tube except the ground to the gray wire I used One of those blue things that I hate but didn't want to cut original wire. The only thing I did different from original tread was I plug into 28 instead of 27 they both are grounds I might try putting it in 27. I PMed GXP asking Him IF he used to 10 amp fuse that he had to take out of27 and put it in fuse able link in his tread it shows a red fuse I used 5 amps but he hasn't gotten back to me yet thanks for the help I'll keep trying
Regarding the use of the fuse tap: There are two fuse sockets on the tap. The one of them that is closest to the fuse block powers the original circuit and should use the original fuse, the other powers the tap, and should be fused for the load that you are adding. It is possible to install the tap backwards, which will cause both circuits to be fed through the "original" fuse, potentially overloading it. To prevent that, first install the tap without the original fuse, only install the upper fuse. If the tap circuit has power, it is installed correctly. If it does not, reverse it and check again. Once you know the correct orientation, install the original fuse.
