Turning Turn Signal output to Steady Output

[Waggy]

I have been trying to find a way to have when my driver's turning signal is on, for my driver side backup camera to show on the monitor. I saw it in a MH a number of years ago. I also thought I knew something about electricity, but I am finding I do not. I have purchased 2 different "relays?" (Tongling JOC-3FF-S-Z, OMRON H3Y-2 Timer) and could not get either to work. I the got off of the internet a "Turn Signal Output to Steady Output article and tried that. I wired it up as per what I understood should work and it did not. Any advice would be greatly appreciated.

Here's how I would do it...

First connect the timer module power input to +12 and ground.

Next look at your turn signal wiring. Locate the wire that goes to +12v when the front turn signal indicator (on your dash) is lit. While you are there look at your watch and determine how long the "off" time is between blinks.

Then look at the timer module instructions. Set the time duration for 10% more than the "on" time from the previous paragraph.

Next, look for an input that when connected to +12 starts the timer. A number of timer boards that I found do NOT have this feature - their only way to start the timing cycle was to connect it to ground momentarily.
Connect that to the front turn signal indicator wire you found in the previous step.

Again, look at the timer module instructions. Look for the relay output connections, specifically the "armature" and "normally open" connections. Connect a test light to those pins. When you select a left turn the relay should close when the first flash on the dash indicator comes on, and goes off just after your stop the turn signals. Don't proceed until this works.

Then look at your camera monitor manual. Is there a pin that when activated switches to the camera you want to view? If yes then... determine if you have to bring that pin to 12 volts? or take it to ground?

Connect that wire to the "armature" pin and the "normally open" pin to either 12 volts or ground depending on what the manual says.

Let us know how it turns out for you.

Fixed!

[AnotherMike]

Good! Now you get to do it again for the camera on the other side...

Nah. I was talking about fixing your post. You put ON when you meant to put off.

Sorry - I thought that your response was from the OP - I should have looked more closely.

And you are correct. I typed on when I meant to say off.

As Maxwell Smart would say, "Sorry About that, Chief".

OP - can you post a link to your "Turn Signal Output to Steady Output" article?

And I should have added this paragraph towards the top of my writeup:

The idea of the timer is twofold:
1) to bridge the gap between blinks of the dashboard turn signal indicator, and...
2) to provide a relay contact output that can be wired to the input selector of the video monitor.

Waggy-

Here's a link to a relay circuit that claims to do what you want:

I got these on amazon $14.00 each, they worked great on the test run to Fla. and back. I've got the delay set for 2 seconds and it resets every turn signal flash until signal turns off then returns camera to normal mode.

I tried this one and never got it to work. I must be reading it wrong. There is no + or - on the capacitor? Does it matter what direction he resistor is wired?

[l1v3fr33ord1]

Waggy-

A resistor can be wired in either direction.

An electrolytic (common, small can-shaped) capacitor must be wired with positive and negative poles in the correct orientation. Three ways to tell the poles apart:

1) The wire lead on the positive pole is longer than the lead on the negative pole
2) The large stripe on the "can" is the negative pole. Sometimes that stripe has minus-signs printed on it.
3) A series of arrows on the "can" point to the negative pole
