01' silverado tow package harness plug

Hey all,

Ive got a 2001 Silv. It has the tow package option, well, atleast on the shifter it does. But under the rear, above the spare tire, there is the typical 4 wires for wiring up trailer lights. But this truck has the wired crimped off. There is no plug there.
Thats my question, where do I get this plug that I can hook those wires into?
I believe its a 7pin thing?

I already have a Drawtite Trailer Hitch wiring T connector (18384). But ofcourse, The vehicle does not have a plug that this T adapter plugs into.

If your truck is pre-wired for the 7 pin connector and a trailer brake controller, Draw-Tite (and others) sell the kit that has a replacement 7 pin connector, and there is a trailer brake controller plug under the dash. Some upgrades also include a 4 pin connector, or you can just plug in a 7 to 4 pin adapter. I have seen most of these parts for sale at Wal-Mart and the auto parts stores.

This is one choice http://www.drawtite-hitches.com/prod...ector,LM-40955
This is the same type of connector from Curt, but it has only the 7 pin connector http://www.summitracing.com/parts/CHT-55774/

For my 2000 Ford Expedition Draw-Tite also offered an upgrade kit that also included the extra relays and fuses for the rear wiring. However, it doesn't look like they sell a complete upgrade kit anymore , so in addition to the 4/7 pin connector you may need to get additional relays or fuses to activate the wiring.

It does not appear to be prewired for the things you mentioned. A trailer harness does me no good without the factory plug to plug them into.

All the truck has is a pig tail of 4wires coming off the wiring harness. I need to find the plug to solder these wires onto, so I can install my T connector.

Before you start check the rating on your truck to see if it will tow the trailer
you want to tow- my 03 silverado was rated to tow 5000 lbs but the manual
transmission version was only rated for 1500 lbs. My girlfriends 08 Ford has
simular ratings- manual trans is only rated for about 1500 lbs. Jim

Just realized that you said it has the tow switch on the column which indicates the auto trans- but check rating anyway as the ratings vary
based on engine, trans, rear gearing, and 4 wheel drive. All silverados
come with the tow switch- it is a transmission function and does not indicate
that you have any other tow components, though I believe the wiring for
the trailer lights is there. Jim

1500 pound tow rating with a manual transmission? With which engine? Are you sure you are not confusing that with the payload capacity? 1500 lbs is the ballpark payload capacity of a 1/2 ton from that era.

327amc, here is a link that shows you what you should be looking for to hook it up:

Ok. Thank you for that. I guess im not explaining this good enough. I need part A in that diagram. I have part B already to go. But nothing to plug it into (that would be part A). Where do I get part A?

Yes I mean tow capacity- many of the 5 speed manuals put in trucks were
meant for towing- check the owners manual. my 03 actually had a higher
payload capacity than towing capacity if equiped with a manual trans, and
the 6 was actually rated to tow a couple of pounds more than the 8 due to
the extra weight of the engine. The automatics were rated to haul about
5000 lbs. Jim

they did that because many people cant drive M/T's correctly and cook clutches towing, and worn out clutches on trucks still in warranty is no good for profits.

Never heard that before. I have a '00 Silverado with a 5 speed and it's rated to tow 10,000. It is a 3/4 ton though.

I'm looking at the 2003 Silverado owners manual right now. Which engine does the truck(s) have? The 4.3 and 4.8 trucks with manual transmissions are rated to tow 3,500lbs up to 5,400 lbs depending on engine and gearing. The maximum trailer tongue/kingpin weight (not the weight of the trailer itself) is 1000/1500 lbs.....

Sounds like someone has mooched your Plug, best place would be a Salvage Yard so you can do the same thing. Just snip one off, shouldn't cost but a few $.

Before you snip it off, why not just take the WHOLE harness and plug it into your harness.
