Wiring help?

Okay guys, gonna do the whole new wiring set-up. Looks like an EZ-wiring kit from eBay is going to do it. Questions..

1) Should I go with 12 or 21 circuit? Looking to run a few accessories, but not too terribly much.

2) What else will I need? Will I need any relays? Or are they all inclusive?

3) Can I remove all existing wires? Will I need anything that is already there? Or will it all go?

Do you guys know the differences between the kits? What's the diff between the $130 kit and the $155 kit?

Thanks in advance!-John

if it will fit, get the 21 circuit. never know what might get added later. more lights, power windows, extra power jacks or who knows what. can also split up circuits so when a fuse blows, only one item goes dead. if you have a little knowledge in this area, parts can be had MUCH cheaper. delcity has anything you could want, including circuit breakers that light when tripped (no fuses)

The only thing I know about diferences in kits is the quality.
Some have crimped wire connectors and some are made with soldered terminals onto the wires. Also some have cheep ass fuse blocks with gold colored fuse plugs and some have brass fuse holders. The wire diameter, number of strands in the wire and the kind of insulation on the wires also is vastly different. (The wire is the most expensive part for the builder) . The cheeper wire sets are typicaly the made in china stuff. There are USA hand made wire kits of very high standars but pricy.

Usualy the you get what you pay for. You pay cheep and get cheep which will bite you in the ass a year or so down the road when condensation and humididty starts attacking everything.
The more expesive wireing kits usuall\y come with all relays, solinoids , fuses, extra terminals, extra wire and the special tools needed for instalation.
By the time you buy all else you need to complete the cheeper harness you will probobly spend about the same or more anyway.

I recomend you make a rought drawing of what circuits you plan to have before you buy. that way you will buy what you need. Don't just geuss at it.

I don't have any personal expirience with Pain less but others who have installed them now refer to them as painfull. They are not soldered connections.

All that being said, the auto manufacturures crimp some conections and solder others. But it the quality of the cripming terminal and the wire its crimped to and the method/tool used to make the crimp that makes all the difference in the world on servicability.

It is recomended that you change all wiring in your van< the one you leave is the one you will be fixing sooner then later.

Amen M1. I installed a Ron Francis GM Express and it is fantastic. Easy to install, overbuilt wire gauge, relays, extra circuits, made in USA. If your budget allows, it will be the last time chasing shorts and grounds!.......an inevitable reality from 40+ year old wiring.

If you don't mind me asking...I was thinking of buying a wiring kit and although it would be a Ford kit, it should have a lot of the same accessories, just wondering on the price for such a harness from Ron Francis.

Big W, just go to the link and look what he has, many options at many prices

I think the difference is the cheaper one is smaller and only houses the fuses and the relays are wired in seperate and the more expensive one has the relays in the fuse housing. I've used 3 of the EZ kits and really like them.

I have a 1968 GMC Handivan 108" WB and have purchased a 21 Circuit EZ wiring harness for it. I have been reading every post I can find on wiring harness installation and details, etc. I have an idea how to do this but it is a little overwhelming to start just yet. I am seeking advice from any of you that may have undertaken this project and have some inside knowledge beyond what the instruction book tells us. Do I basically take out everything and start fresh? I am also going to be using a HEI distributor and 100 amp one wire alternator and am running a 307 V8. Any and all advice is very much appreciated.

yes to removal. yes its a little overwelming - just lat out the new one & mount it before strippimg teh old out - so u have a sort of idea where & how its run. were all here to help.

Thank you guys, this should get me pointed in the right direction...
