Which brings me back to the first and last comments I put in the first post, to save you all the hassle It was
'Let me start by saying I'm just letting everyone know of my experience so they can be wary of buying something on a forum."
and "caveat emptor it seems. "
The above means buyer beware in latin for those who don't know.
The car it was plugged into at the time was a 185 with a gen3 swap, for interest sake I've also tried it in my 205 and obviously the same happened.
To follow on from the previous post, the sellers are still liable, regardless of it was knowingly or not they sold an item which wasn't as described and therefore in breach of the acl.
No throwing up legal words and what not will not get the issue solved. But it might make others wary of buying items off others, regardless of who they are.
