engine wiring

[Bob Gil]

I am wondering (thinking out side the box) most engines have the wires running along the valve covers on the tops of the heads.

Would there be any thing wrong with running the wires across the top of the engine compartment and then down the front of the engine to where they need to go?

I have found my wires to the water senors on both heads now i am about ready to run the wires. 

One thing I have found that is funny one of the gauges reads 10 degrees higher than the other no matter which head it is hooked to , or what the temp is.

on my Eagle (6V92 auto) the wires run down the center tunnel of the bus that is under the floor and above the baggage bay. from there they run to the passenger side attatched to the floor structure to the rear and drop down at the rear directly to where they attach. at no time are any of my wires touching the engine other than at the sensors or starter.
good luck

If the wires go directly from the body to the engine senders, might be a good idea to attach the wiring to some part of the engine so that the running vibration is not transmitted to the wires at the sender terminals.    Any attachment point a few inches from the sender would work.   Stress relief is the goal. 
Otherwise, you may have a good bit of trouble with loose wiring terminals and connections...down the road...some dark and stormy night. 
You've probably already done so, but all of the terminations should be heatshrinked...heatshrunck?   
There are some nice terminals that are full of sealer and have the heat shrink made onto the terminal.   They'll last for years without corrosion or loosening up.   
Standard crimp-on terminals are an abomination.  They're garunteed to form corrosion, loosen up, and change (increase) the resistance of the terminal. 
Wrapping all of the engine wiring in plastic split-loom also adds to protection for the wiring.
Split-loom can be bought cheaply on Ebay.   You'll find 100' priced about the same as 10' in the local auto supply house.   Combine sizes and you'll be ahead on the freight.
