maybe somebody can help me out . i hooked up my shield into the plug behind the tach the other day and ran into a problem. although the shield seems to work a little it still seems to fog up on me. i never had this problem when hooked to my other sled. does any body know how much current this plug should have. my shield wire did fall and hit the running board and sparked and then the lights flickered. i hope this didnt hurt anything. everything else seems to be ok. please somebody help me out.
