I just bought this conversion (off road only yada yada) for my 02 Suburban. Relay, wiring, t-taps, etc. for 50 bucks. Stock bulbs or whatever bulbs you want. Made by P***less.

I called them to see if they had a kit for c5 Vette but it's just for trucks I guess.

It took all of 10 minutes to install & I can see at night. Like "back in the day" when you low's stayed on when the high beams were on.

It seems like some smart guy could do the same for the c5's. Any takers?

 

Painless wiring makes a harness. Do a search, or I think summit sells it. Someone also did a DIY with radio shack relays.

 

Painless does not have for c5 Vette, I called them direct.

Thanks.

 

easy as adding a fuse and a relay and a few wires. I have a post somewhere in C5 general which shows how I did it.
then I went a step farther and went for "hex lights" wired up the fog lights to do the same, all 6 on at the same time with the brights...and all are HIDs also

 

Do you think the kit I got for the 02 Suburban would work? That's all it was. It was only on the driver side & I think that the relay got switched on by the high beam signal & sent power to the low (and of course was fused & grounded).

I'm not EE but it seems like it would work for any quad system.

Somehow it "energizes" the right side also.

Could you confirm that I am thinking right? I may just buy another painless kit & try it. The wattage is close (or identical) between a Suburban & the vette.

 

Not listed but again, do a search, it has been done with another painless kit and/or radio shack stuff.

 

I tend to agree with you that the same kit that worked on your suburban should be adaptable to work with your C5.

 

I would not use the Suburban kit, a C5 has special electrics.

Eckler's sells a kit for $50, it is part number 44522.

Thanks OLD Vetter. Looks very similar, but goes to the alt & bat.

I'll try one.



Same price.

 

You are welcome, glad to help.

 

Post 30 connects to Batt with a fuse, post 85 connects to ground at engine, post 87 connects to (engine side) of fuse 10, post 86 (trigger wire) connects to fuse 9. IT DOESN"T WORK! I believe the HID's have something to do with the problem. Post 30 measures 12.09 VDC, post 85 measures 1.15 OHMS to ground, on low beam post 87 measures 10.77 VDC, low beam post 86 measures .01 VDC, on high beam post 87 measures 3.65 VDC, on high beam post 86 measures 6.30 VDC. I must have missed something.

 

This thread is from 2007. Perhaps it would have been better to open a new thread for your problem... anyways, this is the wiring and a summary of your measurements:



Post 30 - 12.09V
Post 85 - 1.15 Ohms to ground
Post 87 (Low Beam) - 10.77V
Post 86 (Low Beam) - .01V
Post 87 (High Beam) - 3.65V
Post 86 (High Beam) - 6.3V

Post 85 with 1.15 Ohms to ground doesn't look like it's making a particularly good contact. Since the wire from Post 85 to ground only carries the relay's coil current, which should be just a few mA, the relay should probably work even with those 1.15 Ohms, but I would suggest cleaning the grounding point and rechecking.

When the relay is actioned, Post 30 gets internally connected to Post 87 and if you have 12.09V at Post 30 you should have the same 12.09V at Post 87 and NOT just 3.65V. Have you tried with a different relay? It might be the relay's internal contacts are not good.

On High Beam, Post 86 should have battery voltage, not just 6.3V. Repeat this measurement and when Post 86 gives you 6.3V, go and check directly at Fuse 9 (check both testing points on the upper edge of the fuse). If Fuse 9 has battery voltage while Post 86 has 6.3V, you have a bad connection at the fuse tap. Both testing points on the edge of Fuse 9 should read the same voltage, if not, you either have a bad fuse, or a bad contact in the fuse socket.

You should do the same test with Post 87 and Fuse 10 while in Low Beam.

If your battery is good, Post 30 at 12.09V doesn't look too good either. What voltage do you have directly at the battery terminals? If less than 12.6V I would suggest fully charging it and taking it to an auto parts store to have it load-tested.

You need to make sure ALL your contacts are good.

 

Thank You. I ordered some inline fuse holder from electDirect, Pt#666263 and I have some new relays and connectors. I will build my own
The tabs are sloppy and my not be making a good contact. I grounded to engine because I couldn't get a reading on the firewall nut.
Battery is on charger and is at 12.96.

 

Glad to be of service! Let us know how it goes


EDIT: regarding the ground point, is this the nut you tried?



You can also try Grounding Point 9 in diagram below. It is right besides the battery and easily accessible if you get to it from below the battery heat shield:
