Yeah, use those stainless studs with anti-seize. And speaking of those studs, our 71 coupe has 3/8" UNF fine, whereas the 72 OTS has a right weird coarse thread. That seemed strange.

I'm amazed you managed to separate the down pipe from manifold. This is what we had to do to get the down pipes off, I just took it off the shop coffee table where it sits as a monument to the task of brute force it took to get it out. It still has your mate the sealing ring on after all that beatin...

Thanks for these answers Gents. I am somewhat mystified as to how a 3-pin relay works, does it energize the third pin to the power signal when on? I cannot find the pin out to that relay online. Either way its solves my issue, as the SBW is long gone in previous owner wiring debauchery actions and I...

Now Sir, I have fitted a denso, by WOSP, and its great, you don't connect the brown/green to the alternator, only the brown/red for the low volt light in Dash and main power Brown. That wire runs to regulator connector, and you need that, as the wire to the light runs from the back of that connector...

Could anyone enlighten me on this relay please? Its on a US spec 72 OTS that had AC, located RHS of tunnel behind radio panel. I am quite sure it is factory wired. It is fed from the non fused side of F6 with a white wire to a line fuse, and onwards to the relay with a Light Green. Is it SBW related...

This is great thanks for all the replies My only concern then seeing as its the reverse of what I thought is that if you are cranking away on some long distance freeway run in a US stylee, you could be with your solenoid OD engaged for many hours (well as long as your fuel lasts). In electrical theo...

Another Q, don't know much about these. Does the overdrive give a rear wheel speed higher than 4th? per engine RPM when engaged or does it place the engaged output ratio between existing 3rd and 4th gear? I always thought that these shifted down rather than up when engaged, meaning the latter would ...

What about the Speedo cable and drive? does that swap over?
Cheers

Sir,

What year is Car?

What colour wires on new switch. Are you sure white/red on old switch is not white/pink?

Cheers

loads of info in there on this install.

Thanks Mark, I should add that I posted that photo more in the relay oriented conversation as it doesn't show the coolcat 2 speed install, that' a different car. But yes I was also going by the much higher current draw figures posted here when I designed my coolcat wiring, hence the diagram above wi...

Yeah there's not much in it, and you are of course right about the cowling! Doh!

Dear Mr. Simon, I don't know if you sorted out your problem with the sender unit after all the responses. We had the same thing with the senders going full scale when faulty, and also the same thing with them being positioned in that most ludicrous spot down by the exhaust. Later models they moved t...

Gents; I agree about the coolcat switch instead of otter, we are using that too with the housing they sell. I find it comes on a little before the Otter i.e. slightly lower output radiator temp. I used two relays for high speed because of the other comments on this thread about the current draw, as ...

Here's my wiring diagram for the 2 speed coolcats job
