Help: Boss kit with indicator cancel/ what rear seats to get?

[ep91face]

Hi lads,

Looking for a bit of help with the last couple of things due to finish on my project starlet.

Firstly im buying an aftermarket steering wheel and im wondering what do i need in a boss kit so that the indicators cancel and the i can have a working horn? if anyone can reccomend a boss kit that does this il be delighted, (cheap as possible

Secondly im replacing the rear seats in my starlet and was gonna just stick 98 spec ones back there, however id really like to have a rear bench out of a car with only 2 back seats and a lump (like a levin) in the middle with an armrest too. I think it could look really well and would save me ever having to squeeze 5 in. (bare in mind losing the back seats is not an option)

Any help or advice ye can offer on these will be greatly appreciated !!
