took a day to put it in and put harness in. i have about 6 wires to hook up int stock harness and run a larger fuel line and put tank in. i just havent had time to do it. my buddy made that harness in about 1 hr. using that diagram. and a question for you. hew much did the welded diff in the front of your 4-runner affect the turning radious on the trail? i have a 85 4-runner and have been debating on this.
