I have read the two articles on upgrading the headlight system to run off relays. But wht is a good part # for the relays? I go to AutoZone and they have no idea what I am talking about when I say "bosch type" relays.

 

There are two good tech articles on this subject.

This one has a good diagram

I prefer this "whiter whites and brighter brights" article:

This is probably where you got the "bosch style" advice. Really, what you need is any old relay that is rated for the right amperage. You probably don't need to talk to the parstman at all, they should just be on the shelf.

Good luck, this should be a pretty simple weekend project.

EDIT: I see now that you have read both articles. Sorry about that. I don't know the part numbers.

 

Have not had any dealings with this group, but they appear to be able to supply all the parts including replacement headlamps (good - cibie) should you want to get new lights to go with the upgrade. They also list wiring diagrams and instructions.

Go to the fog light section of the auto parts store. The relays should be there. They might be sold as part of a fog light instalation kit.

 

I have seen in !#@ Truck catalog has a relay upgrade that you plug into your trucks wire harness.(runs like $29.95) I KNOW THIS COMPANY DOES NOT SUPPORT THIS WEBSITE. I'M NOT SUGGESTING TO BUY FROM A NON SPONSOR, but they are avalible for our trucks, and some people are not as inclined as others. Possibly there is a supporting sponsor that does sell this part.

 

That's kinda funny! Did they have the "deer in the headlights" look? There are tons of different relays with tons of different applications, and yes, Bosch makes tons of relays. LOL

From just looking at the pictures, I like the second article better-but that's just me. The second article mentioned a 20 Amp fog light relay, as did 76supercab2. A pair of 12 Volt, 20 Amp relays should be more than adequate for the electrical load involved. Like mentioned, these relays can be found in the automotive lighting section of any auto parts, most any local hardware or even Wallyworld. I think they run $3-$5 each new. The packaging usually has some illustration showing pin locations and identifiers, along with pertinant electrical info.

My-self, I go to the self serve yards, take a Multi-meter and harvest a few fan relays @ 60 Amps each. They may charge me 50 cents, they may not; I'm cheap.

 

You can buy the relays from Painless and Waytek.

Here a nice setup for the relays and fuses https://www.ford-trucks.com/forums/4...elay-pack.html

I bought the relays at Carquest and the fuse panel at Autozone.

You can also buy Bosch relays at your local electronic parts store.

 

If you can find these things it would simplify the setup:

I finally did find the relays at O'Reilly's. THanks all for your help.

 

Buy and keep an extra one with you. I've had a die on longer night driving trips even though I am well under the rated amp load. Finally went to the porsche dealership and got some good quality ones.

 

The actual Bosch relays are high quality but there are a lot of knock-offs in the same form factor.
