The cylinder head temp gauge works by the wires actually generating a small
voltage when heat. That is why the can not be changed at the spark plug end.
The oil temp gauge uses an RTD (resistive temperature device). Normal wiring
methods will work fine. Just make sure all connections, particularly any
grounds are clean and tight. What range of readings are you getting? Head
temps to 450 and oil temps to 270 are not uncommon. I do agree that these
are not acceptable but I have seen these readings often.

I recently installed a set of VDO gauges and I've had some minor
inconsistencies on information.
The VDO cylinder head temp says *Don't shorten the wire in the kit". I'll
go along with that.
There is also a wiring installation kit for the VDO oil temp kit (I
didn't buy) and I was wondering if the oil temp was as critical as the
cylinder head temp as to the actual wire used to activate it. I'm using
standard automotive wiring for the oil temp gauge, I'm not liking the
high readings I'm getting and I'm certain that they are currently
incorrect.
