rdog30 · 03-03-2009, 04:01 PM

Have any pics of it? I think it's almost just like the impala/caprice harness.

irocboy8292 · 03-03-2009, 08:26 PM

yea pretty much the same thing but all i see on the stickies is the f body one not the impala one

Does your fuse box look like this? If so, put a cable from your battery to the post on the right, wire C2 to your fuel pump wire,wire G1 to a switched ignition source. Leave your purple ignition wire that was going to your starter the way it was. Use the batt. power cables if you have them. 1 goes to the starter,other goes to that post,and the other goes to the alt. Get vats tuned out

irocboy8292 · 03-06-2009, 10:04 PM

yea it kinda does look likethat .. but what do you mean by "Leave your purple ignition wire that was going to your starter the way it was. Use the batt. power cables if you have them. 1 goes to the starter,other goes to that post,and the other goes to the alt."... also i got a vats bypass module so that is solved already

rdog30 · 03-07-2009, 12:13 AM

Batt. cables from the swap car. You will need to have your batt. on the passenger side if it's not already there. Your cars ignition will work just the way it was.

irocboy8292 · 03-09-2009, 09:19 PM

ok just to be clear... from the battery to the post?... from post to the starter and also to the alt?

rdog30 · 03-09-2009, 09:41 PM

What I'm try to say is use the power cables from the fleetwood. It's 1 cable that splits into 3. 1 to the post on the fuse box. 1 to the alt. 1 to the starter.

Go look under your camaro at the starter. There should be a purple wire and 2 red wires down there. When you get the lt1 in, wire it up just as before. I opted to move the 2 red wires to the post on the side of the fuse box. The purple wire is your ignition wire. The 2 red wires power your interior and exterior lights.

Are you using the lt1 starter or the one from your camaro?

irocboy8292 · 03-12-2009, 01:54 PM

iam using a powermaster some what smaller than a lt4 starter.... i get the whole battery cable thing how do i run the fuel pump relay though

rdog30 · 03-12-2009, 05:52 PM

Under your dash there is a clear connector(c207) next to where your old computer was. The wire for the pump is in there. Do a search for c207 for your year camaro. run a wire from that wire up to the engine bay and connect it to C2(gray wire) from the 37 pin black connector. If you can't find the diagram you can always trace the wire from the fuel pump itself.

irocboy8292 · 03-13-2009, 05:30 AM

ooh but wouldnt it be different since i was carb?

rdog30 · 03-13-2009, 05:49 PM

in that case your going to need at least a tpi in-tank pump. I don't really know anything about carb cars. Mine was already a tpi when I did the swap.

irocboy8292 · 03-13-2009, 08:56 PM

yea i know iam in the process of getting the tank and already have the pump from a stock lt1 just wondering how would i run the relay..? also was looking at my harness and notice i have a plug with 6 thick red wires what do i do with that

rdog30 · 03-13-2009, 11:08 PM

The fuse box already has the relay in it. I don't think the 6 pin connector goes to anything. Try lt1swap.com for some wiring diagrams. look under the impala/caprice section.

irocboy8292 · 03-14-2009, 11:27 PM

thanks alot you dont know how much you have helpedd me!

is the fuel pump relay one of the two that hang on the side or it is inside?
thanks

rdog30 · 03-15-2009, 01:46 AM

Inside. It's labeled f/p Letter E Should be the black one.

irocboy8292 · 03-15-2009, 08:50 PM

was looking at my fuse box it is quite different.. it has the post inside instead of on the side also the only relay inside is for the air pump then on the outside there is two relay clipped on the side a green one and a dark gray one..... you get which one iam talking about?

thanlks

irocboy8292 · 03-16-2009, 10:49 AM

do you think the fuse box i described above has a fuel pump relay too?

rdog30 · 03-16-2009, 05:43 PM

I've tried searching for it and can't find anything. You can try going to autozone or some place and have them look it up, or get a chiltons manual for the fleetwood. One of those relays should be for the fuel pump.

irocboy8292 · 03-16-2009, 07:49 PM

i work at autozone and never thought of that lol... i also noticed a black one that had a gray wire a orange wire a red wire a drk grn and white wire a black wire i think that one it is i will do as you told me and check in autozone

irocboy8292 · 03-17-2009, 04:34 PM

you think that could be it
