The hook up of GPR is (from the bottom to TOP) - first Bottom - all ORANGE wires, next small PINK wire on small post, next small BLUE wire on small post, Top - RED power source. Red wire will be from Resistors
(OR) like in this picture from the 12v terminal block (diamond shaped).

I need to replace my relay, what is the difference? Is the relay from Napa worth the extra money?

I have installed the s603 for 28.00 from AAP Advance Auto Parts
on 3 blazers, works fine - price is the difference.
Unless someone would like to chime in on this post?
Have at it, enlighten us.

I used this one:

Worked fine for over a year now.

Ok do i need to replace my GPR?

When i turn the ignition to on i hear three clicks about 5-7 seconds apart, wait light goes off, then i start my m1009. But after she's started the GPR continuously clicks. and i have popped the hood and felt the GPR clicking. The 1009 does this hot/cold, idling or running for about 30-45 second after every time i start.

Here is a pick of the GPR i have in my m1009.

I would, cheap enough. You may want to do the resistors bypass as well. Unless you plan to jump or be jumped by a Military slave cable. I carry 2 sets of jumper cables - one for each battery. You can move that red Power Wire from Resistors to the 12v terminal block up and to the left slightly from the GPR. You have to drill the eyelet out slightly to get it to fit over the left bolt on that terminal block. Oh, First step - take the Red wire off the 24volt terminal buss block, it's to the left (Left Side) of the Resistors.
