(I also posted this also in the other thread.....DIY timer install...)
Thank you very much for the diagram, it makes it much easier to understand. Very professional diagram I may add! Your knowledge on this is great! I am so glad to have met you and have the luxury of someone already figuring it out.
I was afraid if i do it wrong, it will be a real nightmare to undo whatever I did???
Seeing as i am using the 7 day coolant timer, which has a manual on / off switch, providing the same function as the switch you installed 5103-853AA(I mentioned to this to you earlier) my wiring is almost the same, but not quite.
The timer has a diagnostic function (shows trouble codes if espar malfunctions), which requires one more wire to the blue wire on the espar heater side of the wiring harness under the battery.
Here is a link to the diagram of this timer wiring diagram,
I have the timer, and the 12 connection plug that plugs into the back of it (that I wire and crimp pins to whatever I need), that you will see it in the link above, at the bottom of the page on the left. I do not have the relay shown, but will get the 4 relays as per your directions.
Can you tell me how my timer wire job will differ from your switch wire job? I do not need anymore diagrams, but just what substitutes for what in my case.
Coolant Heater timer connections:
there are 12 terminals, not all used. You will see them clearly from this link.
here is what I can put together:
term 1: to splice of other switches grey/green/red for timer light display
term 2: wire output to relays (all 4) #85 term of relays
term 3: empty
term 4: splice to - battery at 12v outlet, plus to #86 all 4 relays
term 5: empty
term 6: empty
term 7: empty
term 8: splice to blue diagnostic wire at heater side of harness under battery (not on your diagram as this gives timer diagnostic trouble codes for service)
term 9: empty
term 10: to vehicle ignition accessories for continuous operation of heater??
Do I need this connection? As per your diagram, your wiring is already addressing this correct? This one I am not sure of????
term 11: splice into + battery at the 12V outlet under switches
term 12: splice into - battery at the 12V outlet under the switches.
The rest of your diagram, I follow exactly.
have I missed, or overlooked, or goofed up on anything?
You also mentioned that I do not need the switch, 5103-853AA, nor the connector 5120-633A, and that I only need 1 terminal, part # 5103 882A.
i will aslo need the 4 automotive 5 post relays, 5 splice connectors blue, plus a bunch of male and female blue connectors, and 16 guage wire.
I am very excited as i know I am getting closer. many other members are also very greatful
