Whats the best wire to use for rewiring engine compartment

[limp]

I have to build a new engine harness for my 83.. Is there a particular kind of wire to use on a Car? Seems I read about auto wire with an extremely hard insulation??
Any suggestions from the Electric geeks on here? TY

TXL or GXL type wire.

GXL is preferred for high heat applications such as wire running through an engine bay. For everything else I use TXL
