those connectors sound great. Car sounds great. When you say "kill the fuel pump" are you just rewiring it.

Adding a tach relay. Relay when triggered runs fuel pump 3 seconds. Then stops until the engine fires. The relay is wired to the tach lead. It will energize the pump as long as there is tach signal. If the engine dies, the relay closes killing the pump.

Is that safety incase of crash ect?

Jeff · February 24, 2019, 06:52:51 PM

Yes. You need a way to shut the fuel off. A mechanical pump obviously stops when the engine does. This one wired to a hot toggle scares me.

thanks, it is good to learn something everyday. Great car and glad it is maken you happy! in the old days there was room under your seat. my bother had a metal drawer under his seat with a switch that ran off the tail light current. it had a solenoid style latch like for rods with the shaved doors. the drawer was spring loaded to open when the latch was triggered. he kept his self defense weapon in there. If he was at the side of the road, he could flip the switch, and then if he touched the brake , the drawer/gun safe popped open from under the seat between his legs. secure, but easy access.

They make a switch that works on loss of oil pressure as well, but I figure the less little oil lines running about the better

Anyone know what the extra blue and green wire might be for on the electric fan relay? They are just folded up and taped to the harness. There is a black ground, an orange power to the fan, a red power to the battery, and a grey wire going to the temp sensor in the intake manifold. I have no idea what the unused wires would be for.

Could it be for an A/C system? They'll usually turn the fan on when the ac compressor turns on.

What might I use this for?

What better way to start to clean up automotive wiring than with a travel soap dish.

This is to convert part of this mess, multiple wires with inline fuses, to one battery feed wire to three self resetting breakers for fan, waterpump and fuel pump.

It's getting better.

How do you like the crimper ? i never knew anyone who had one. I like the battery terminal.

Jeff · March 14, 2019, 08:47:13 PM

Used it just once to make that 2ga cable. Got it for less than 25 bucks at harbor freight. I have some winch cables to fix, so I figure it will get used more. I have some ground cables to make yet as well.

looks like the right tool for the job. You are doing it right. If you use it 25 times in your life, that is only $1 per connection.

AZ_builder · March 14, 2019, 09:14:52 PM

I like clean wiring and your looks clean! Most folks would just add to the nest, I'm glad you have pride! Now you just need to get an interstate battery in that car to run all the extras :-)

Peter Drouin · March 14, 2019, 10:24:01 PM

Cleaned up nicely, Never seen a double hot fixture like that.

Jeff · March 15, 2019, 06:58:00 PM

I have my homemade relay box finished and mounted. I also added a ground bus. The old wiring had grounds run all over. This allows the grounding of all those go fast electrical components to be grounded right next to the relays eliminating a lot of wire runs.
