First question ....
I have a console gauge group [voltage, clock and oil temperature (cels)] that I want to install. Beginning today with the oil temp., I see the brown wire as ground ... black as 'power' ... and green/black as to the temp sensor on the rear of the 1.6L engine in the head.
I have a fused spin ... up near my neck, and flexibility is in short demand. I presume the best way to connect this gauge would be to remove the fuse block and connect to the rear. Never have taken one out yet ... presuming this of course ... but not a workable option for me. Also taking the instrument cluster is not one I cherish ... even though have done it in the past ... due to brittleness, etc.
That appears to leave the only option as going thru the firewall with a separate wire and splice into the wire at the sender. But this seems to me as not so good, since it would be 'around' the applicable fuse.
Is this a good move ... or is there a better choice that I should utilize?
What is in jeopardy doing this?
At the same time ... in looking at the sensor today, I recall wondering in the past why there are 2 sensors in the water flange that feeds the heater ... with separate wire connections. I realize this may be common knowledge ... but I admit I missed that trolley car.
Second question ....
Using the same facts of above, where would you suggest I safely connect to the battery 'hot' in order to activate the voltage meter?
And lastly with 'second question' in mind ... for the clock ... would it be OK to hook up to the same 'hot' (red) wire connected to the battery for power ... and ground to brown wire?
That leaves getting on-off power to the lights for these gauges ... which I have not contemplated as of yet.
