For oil, AM has the 1/4" adapter to screw into where you remove you stock sending unit....I believe a 15/16 or 1" open end will remove the sending unit...remove your oil filter as stated for easier access...
IF you dont want your stock gage dead, then you need make a Tee to put the stock sender back in place...it didn't like having dead gages so I did mine up..
Head to Home Depot and round up, 1/4" x 1" long nipple...a 1/4" Tee and a 90 deg street 90 and some thread sealer...remove the stock sender, screw in the 1" nipple...screw on the Tee, then the 90...See my pic and you'll get the idea..
What you need....
With the stock sender back in place...you need to add some lenght to the wire to reach..
This one you can see where the adapter in your AM kit screws into the 90 and that your gage line....
IF you have a temp gage, youll need an adapter for the AM sender to fit...it wont fit in your stock adapter...i found that out AFTER I tryed to make the connection...I ordered this thru Summit....Use thread sealer on all connections...
For power...I tapped into my parking lights on the drivers side and used the Green ground right at the battery...I also used these bullet connections all around....put these right on the 2" lenghts of wire out of the gages...this way you just make runs of wire and plug em all in right in the engine bay......if you need to remove a gage for a light or whatever, you just unplug it....works sweet..
