Hi Willis Faithraven2007@gmail.com,

This thread started and ended in 2004.

Volvo Tips is a resource. Yet I can't stand the ads (so we use uBlock Origin ad blocker).

The Volvo Tips site content manager converted the original Volvo factory service and technical documentation (in scanned or published directly to) PDF files is in Adobe Flash files. You need the Adobe Flash or Shockwave driver to see some Volvo Tips content in your web browser.

As you may know, most browsers no longer support, or won't allow, Adobe Flash and Shockwave files to play in FireFox, Chrome, Edge, and other browsers. The Adobe video playback software for web browsers has seemingly unending security issues.

I sometimes download the files after accessing the HTML Volvo Tips pages, use the current flash software, and view the content on my local hard drive.

Headlight Relay

You do not need a Volvo 240 headlight relay.

You can use a relay and fuse setup meant for the current load that thrives in the under-hood (weather sealed, heat tolerant) or passenger cabin. You can then use the circuit to delivery full fused B+ power to the low and high beam headlight filaments.

Some oft mentioned resources in the modern moment ....

Mekartips for Mitchell Service and other 100 (140, 160), to 900 series wiring diagrams, and other info:

Want any or all years of the Volvo 164 factory 'green' service manual in PDF and other info?:

http://www.240.se/litteratur/service100.htm

Tho now I'll never own a 164 as I'd been hoping since before the 1980s.

The Oz Volvo Technical Archive (not quite what K-Jet.org was at all)"

https://ozvolvo.org/archive/

And other resources ...

Hope that helps.

>31b is the toggling trigger -- momentary input only, or you'll fry it. This is the wire from the turn signal switch that's normally not connected on U.S. market cars. Find it taped up by the wiring harness above the left fender near the firewall.

The grey wire.

>15 is fused power, used only to flash the high beams with the light switch off.

>81a gets jumpered to 15.

The black wire next to the grey wire. Find the other end of the black up by the fuse box and plug it into the lowest fuse, inboard side.. Re-wrap the double red.

>56 is power from the headlight switch.

The yellow wire, once you've snaked the dipper wires out the firewall.

>56a is power to the high beams (or armature power to a high beam relay).

Double red wires formerly on the dipper.

>56b is power to the low beams (or low beam relay).

Grey wire formerly on the dipper.

Thanks Phil
