Ok Guys,
I've done many many many searches here, where Ive found many threads, but none have fully addressed my current woes.
Installing a set of JDM Folding mirrors into a 2000 Lexus SC400 for a customer.
Want to avoid the Viper591XV alarm and go with a direct wire setup. Looking for the mirrors to fold out with car started and fold in, once the ignition is cut.
Will most likely tap an accessory wire here.
The mirrors did not come with a relay box or mirror ecu, furthermore both mirrors are operated on a simple 2 wires setup.
Power moter- mirros fold out, Reverse polarity and the mirrors fold in.
This is really 3 problems in one. I have a rough idea of the setup I need:
Problem 1:
Latching relay- Dont want to use 12V DPDT PC relay setup as it is manually controlled with a toggle. Mechanical latching is ok, but not convenient in regards to time- dont think I can get locally.
I think I will build a relay setup similiar to this to address the issue (uses alarm pulse though
)
Problem 2:
The mirrors have to be on a timer because they have to turn off/on at a specific time (2.80s) to prevent them "overfolding"
I will link the setup to a DEI (528T?) Timer relay to control the duration of power.
Problem 3:
I want to be able to "override" the ignition ON feature, when backing into a 1 car garage or other tight spots. A simple switch linked between the accessory wire and timer should address this.
So I am thinking it will be like this:
Latching Relay (Reverses Polarity) -> DEI Timer Relay -> Override Switch -> Acc
**I do not think I have something that will power the mirrors IN once I cut power from the Acc**
Can someone please look this over and give fill in the spots Im missing...
Will I have to use the alarm? Not possible for a direct wire?
Any suggestions??
