sdsurf Posted July 3, 2009 Report Share Posted July 3, 2009 (edited) I have 4 wires coming out of the harness for my 521. 2 are attached to the plug and 2 are free. Of the 2 that are free one is black and one is yellow (faded white?). On the alternator there is "E" on one post and "B" on the other. which wire goes where? The haynes harness says black to "B" and the other to "E". this seems bass ackwards. Is that correct? the pic below is from another post. Is this correct?

dat521gatherer Posted July 3, 2009 Report Share Posted July 3, 2009 that is correct the black one is the ground. the wiring diagram in the haynes manual is for a 620 even though it says 521. this is stated on the first page of the fequently asked questions thread in the general discussion. i got rid of my haynes and now have a factory 521 manual. they come up on ebay all the time and last i looked the book store next to the tacoma dome had one for sale. also the owners manual has a wiring diagram also. i keep a copy in each glove box on my 521's just in case i need to take a peek.

sdsurf Posted July 3, 2009 Author Report Share Posted July 3, 2009 thanks gents... on your negative off the battery is there a spare wire coming off the terminal or off the other end? if it is off the terminal where does that wire end? Quote Link to comment
