Fender Jaguar Pickups

If you are installing new pickups in a Fender Jaguar you should always check the resistance of each pickup with a multimeter to make sure that the pickup with the higher resistance goes in the bridge position and the pickup with the lower resistance goes in the neck position. A couple years ago I bought Fender American vintage reissue pickups for my CIJ Jaguar but installed them in the wrong position. I was never able to get good balance between the pickups. It ocurred to me that I should check the resistance for each pickup. I desoldered each pickup and measured 6.38K ohms for the pickup I had installed in the bridge position and 6.58k ohms for the neck pickup. The rule of thumb is that higher resistance values produce more volume. The idea is to locate the higher output pickup in the bridge position where the amplitude of the string vibrations is smaller, thus balancing the pickup output. I couldn't find any values for vintage Jaguar pickups on the intertubz, but Lollar Jaguar pickups are listed as 5.8k ohms for the neck and 6.3k ohms for the bridge and Seymour Duncan vintage Jaguar pickups are listed as 6.5k ohms for the neck and 6.8k ohms for the bridge. My preference is to have the two short extensions on the claw under the low E and A strings, which is consistent with the orientation the claws on vintage Jaguars. CIJ and MIJ Jaguars often had the claws reversed. You should also adjust the pickup height such that the bridge pickup is a bit closer to the strings than the neck pickup, but most of this is according to taste.
