Monza (Stack) Elise S1? - Wiring Help (Grafting To Kit Car)

[Roy_D]

Lello Ladies and gents,

 

I have a 'Stack' 'Monza' IP from either a S1 or S2 Elise and I would dearly like some help - Apologies for the following.. I would love to graft the beautiful Lotus IP into my kit car. [it is NOT my intention to offend anyone here].

 

I have 2 areas to consider:

 

1. How can I get the indicator light on the IP to work? (feeds / Pins required?)

2. Which (Lotus) sensors will I need to get the correct readings for the Lotus IP to work? (Not including Engine management)

 

Lotus have basically said that they do not wish to help (and why should they) and Stack have referred me to Lotus.

 

Below are my findings so far - the IP looks just beautiful when powered up ... but alas, it is on my work-bench! I have looked and looked over the internet and I just can't find the detail I am looking for.

I hope that the above does not cause offense to anyone - the findings above are my personal (Laymen-esque) thoughts.. please do not take them as gospel (and blow up your own IP's).

 

If someone has any suggestions (constructive please!) then they will be gratefully received. (yes, I will have an Elise one day.. but until then, the kit car is my little toy)

 

Thanks and regards,

Roy

B4, seat belt switch and then to ground.

B8, Ground ( other side of rear fog LED inside stack )

B2, is labeled as new spare ?

Hello Gents!,

 

Paul - Thank you!

 

 

Martin, thank you for the information. No, there is no label anywhere on/near B2; should there be?

 

The real 'sticking' point I have is that I can't work out how to get the indicator lights on the dash working. Any thoughts?

 

Thanks and regards,

Roy
