Liam throttle potentiometer is your accelerator pedal and the other I'm not too sure, did the codes come back after deleted?
Looking good Gaz, I wouldn't take your door cards out until you have something to cover them, could properly f**k you up in a bash.
Also if your seats are bothering you then refit the standard spacers on the inside (exhaust tunnel) they some times stick on the standard seats when you take them out. OMP subframes are designed to be fitted with these. I run mine squint so I can get my winged seats further back.
Hopefully the weather is good, I have never had a dry day. You never know with Knockhill though.
