1969 Series 1 Fulvia Coupe Rallye S Wiring Loom Help Needed

[Shelley]

Hi,

We are currently having my late fathers 1969 RHD Series 1 Fulvia Coupe Rallye S restored and need some help regarding the wiring.

The company restoring it for us advised that as it's a "bare metal" restoration it would be advisable to replace the loom. As we want the car to be as reliable as possible once it's finished we agreed to go ahead with this. The restoration company found that replacement looms were available from Autosparks and so went ahead and ordered one at a cost of around £380 + VAT

Once it arrived they then advised that it was not correct for our car as it was a late S1 and so it would require modification to make it usable. The loom was then sent to another company which was meant to have made the modifications but this seems to have stalled and there has not been any progress for some months.

To try and to break the deadlock we find ourselves in we have been looking into this and have found that Autosparks offer 2 looms for RHD Fulvias:

1). Autosparks Part No LC15c
Fulvia 1.2l Coupe
1965 onward
Suitable for Chassis Numbers in the series 818.130/131
(see : https://www.autosparks.co.uk/finder/car/lancia/fulvia+coupe)
This is listed at £510.22 + VAT on their website

2). Autosparks Part No LC20c
2nd Series Fulvia Coupe Rallye
1970-1972
Suitable for Chassis Numbers in the series 818.630/631
(see : https://www.autosparks.co.uk/finder/car/lancia/fulvia+coupe+rallye)
This is listed at £384.63 + VAT on their website

Our car is a 1969 Series 1 Rallye S Couple, with a chassis number in the series 818.361

Given we were invoiced for the £384 loom (less a discount) from the restoration company we are now wondering if they have ordered the LC20c part which appears to be for a S2 and if it is this that is actually the issue.

If this is the case then our main question is would the LC15c loom, which is listed as being suitable for chassis numbers 818.130/131 (i.e. Normal S1 Coupe) also be correct for the Rallye (818.330/331 chassis numbers?) and Rallye S (818.360/361 chassis numbers) ?

Looking at the helpful colour diagram of a S1 loom that can be found on this old topic on this forum:

http://www.lancia.myzen.co.uk/forum/index.php?topic=11747.0

It would seem that the wiring for the 818.130 and 818.330 chassis numbers is the same?

If this is the case is the wiring also the same for 818.360/361 chassis cars like ours and to resolve all of this all the restoration company needs to do it actually order the LC15c loom?

Any help anyone can provide would be very much appreciated as this has held up our restoration for some months now (which was already running over a year behind schedule!) so it would be great if we could get this sorted.

Many thanks in advance,

Shelley

Would a used s2 loom be of use?

The S2 loom is totally not appropriate for S1. There should not be any (or very minor) differences on S1 coupe model variations. 99% should be plug and play. And differences can be accommodated when installing.

I have installed the auto sparks loom in my s1 and as Tim has said it required very minor adjustments, if memory serves a few colours were different to the drawing

Time to get a test lamp or multimeter out methinks along with a wiring diagram...if you have a user manual that came with the car is there a wiring diagram in there?

Hi,

Thank you so much to all who have replied and for confirming our suspicions that the LC15c loom would be the best match for our car.

We spoke to the Restoration Company and gave them this information, however they said they were informed that the very "late" Series 1 Rallye S coupes "had a different gearbox connection" that was closer match to the S2 and hence the S2 loom would be a better option. This doesn't seem to make much sense as, as we understand it, the S2 had a 5 speed gearbox whereas all of the S1s had 4 speed ?. Either way they still didn't seem convinced that the LC15c would be correct.

Since our request to cancel the modifications to the S2 LC20c loom and order the Autosparks LC15c instead the company making the modifications have suddenly "woken up" and decided they can get it completed by the end of next week and the modifications will be complete replacement of the effected circuits rather than "cut and shut" connections, though obviously once it has all been taped up again it will be very hard for us to tell

Anyway, at least progress is being made again!.

Thanks again,

Shelley

I am confused as to why the gearbox has anything  to do with the loom if your car is a s1 then you need an s1 loom for a start the fuse box is located in a different place to the s2 therefore the s2 loom would need to be heavily modified to fit and that’s just for starters , I would be very concerned if someone told me the gearbox has something to do with the loom , unless I’m missing something

Revers light on the Zagato?

(Also Lancia used some weird electronic Solex on some cars to reduce smog, if I recall correctly the did something (running lean?) when the car was running in top gear (or the two highest).  I have no idea when they were used)
