You don't have to use the knock sensor BTW, doesn't seem to bother the computer if you leave it out although it would obviously be a desirable thing
My advice: Use either an EL dash/engine bay loom as Low NA has done, or if you want to keep the dash the same, use an EBII or ED dash and rune extra wires for the thermos. The EL computer will fit the EA-ED computer plug, but you will have to add wires for the thermos, BBM, and K/S, and move the P/S wire.
Depends which way you want to go, using the EL dash is mucho easy but if you don't like then the ED + a little wiring.
