Folks, I need to do what I've been putting off for way too long, install headlight as well as starter relays in my 1750 GTV (Euro, with the inner lamps functioning as high beams concurrently with the outer lows, not sure whether this matters from a relay perspective) and Duetto Spider.

I think I can find how to do it by doing a search on this board, as a lot has been written about it. My question is, what is a good source to obtain them, I can't seem to find them with the usual suspects.....

Thanks!

Ebay is a good source, I bought a box of them with the pigtails for not much money, maybe a little better than $2 a piece. I have read that Bosch is no longer making the relays, that Tyco now makes the bosch relay, is there any trueth to this? I guess a relay is a relay is a relay....

Any autoparts store. I'd buy sockets that facilitate mounting on the inner fender, along with the relays. Makes for a nice and neat installation, and if you ever have to replace a relay you won't have to dink around with trying to figure out which wire goes where.

funny that you mention that, I also though "a relay is a relay" and went to PepBoys...they asked me for year, make and model, and that was the end of the conversation...could not help me:mad:

Walk over to the electrical section. Our local Autozone has a pretty good selection of relays, sockets, fuse holders, etc.

All you need it a generic relay, 6 or 8 pin, and that's it. (If you get an 8 pin, you're only going to use 6 of them anyhow). Oh, and you'll need two of them, one for the high beams and one for the low beams.

I modified a Series 1 10544 color wiring diagram to include three headlight relays. If you'd like a copy, let me know.

Euro/US GTV differences

Don't the European market 1750 GTV's already have headlight relays? American market GTV's all had very different wiring---much heaver gage than the Euro version, for instance---but no relays. I just naturally assumed that, with the smaller gage, the Euro versions had relays.

Also the headlights on the European 1750-2000GTVs are model specific: outer light are low beams only, inside are high beams only. The buckets are also completely different. Unfortunately, my headlights are badly corroded and have to be replaced.

Question: how do you adapt the European model GTVs to take modern US mount quartz halogen lights which are substantially cheaper than the Euro style repro lights? I know it's possible to get repro Euro style lights right now, but I have this cool looking set of NOS US style, Marchal Ampilux q/h headlights. I have some US style buckets. Is that all I need for a conversion?

I am not sure about how to convert. I will check again whether I have relays, but I don't think so. Thanks!

The long answer is...no. (sorry, couldn't resist :rolleyes:)

According to the both the Euro and US version Series 1 GTV wiring diagrams, both versions use 1.0 mm/sq wiring for the headlights from the fusebox. What was actually fitted to the cars though is a different matter.

Also the headlights on the European 1750-2000GTVs are model specific: outer light are low beams only, inside are high beams only.
Yes, this is true for the Series 2 1750 and the 2l. These models were equipped with H1 bulbs. The Series 1 1750 however was fitted with twin filament BiLux 40/45w bulbs in both the outer and inner lenses. The inner bulbs though used only one filament.

Yes. I believe all that's needed is the US version buckets and a bit of wiring the back of the bucket.

Please PM me your email address and I'll send you the diagram.

I just put headlite relays in my 1073 Berlina. I used the 164 relays with the built in fuse holder. I used 4 relays, rt and lt low and high beam. The relays with the built in fuse may a neat installation.

OK, it seems that the Hella HL87121 is available, and a good solution for the headlights. What specific part have you guys used for a starter relay?
I have been procrastinating, but my ignition switch is really on the way out :eek: and I need to get this done
