I have a 2001 Prerunner V6 SR5 TRD (93K miles) and the trailer running lights will not work when pulling a trailer (breaks and turn indicators work fine). They have worked in the past. I used a volt meter and I'm not getting power at the pug. I've checked all fuses and can't find the problem. Any suggestions?

Also, my transmission is making a noise when not under stress. If I'm just maintaining my speed on the highway it makes noise. If I let off the gas or get on it, the noise stops. It's not the front end or axle rap. Any suggestions?

I'm greatful for any help.

Thanks

Does the noise sound like a squealing fan belt?

If it does, the zirc fittings on the driveshaft need lube.

Hope this helps.
As far as the lights, I have Altezza's on my 2000 V-6 TRD Prerunner and after I pull a trailer I have to replace the bulbs because they burn out. Who knows?

Yo-

I Had The Same Problem For 6 Yrs. With My Trailer Lights. I Have A 98 Taco Extra Cab And A 04 Double Cab. And I Pull A Detail Trailer With Both Trucks On A Daily Bases.what You Need To Do Is Go To The Dealer And Get A Factory Wiring Harness And Junk The Pep Boys Harness!it Costs $160 For My 04 And About $120 Or So For My 98.its Eeasy To Install And Plugs In To The Stock Wiring Harness.both Of Mine Have Been Working For 4-5 Months Now.

I just installed a receiver hitch and wiring on my 2001 crew cab. I used the hoppy wiring that just plugs into the tail light connectors (no cutting). Reading the above posts ... can I expect to keep burning out bulbs ?!?

I was wondering if anyone has any information on the 'factory trailer' wiring. Does it also go to each tail light or does it have just one plug that goes to a central location ?? Is there any internal electronics or is it just wires and plugs ? $120 sounds kind of exspensive for just wires. I don't have a trailer but on the VERY rare occasion need the ability to tow one. I hate to spend $120 for nothing but also don't want to have to change bulbs everytime I tow a trailer .... or possibly damage the truck wiring.

PS. I only just installed the hitch so I don't know if it will burn out the bulbs yet.
