Electrical connectors to trim servo. What R they?

[danielabernath]

I'm replacing the trim servo as someone pushed the NO PUSH NO PUSH trim on the stabalator and snapped off the screw on the servo.
I have now encountered this. Can you identify this and tell me what should be done next?
The new servo has bare wires and all are colored except TWO of them are white. An a&p told me that if you hook up the wrong white to the wrong white then it will be backwards (push up and the trim will go down) Anyway to do it right the first time?

Also,
1. how do I separate the old servo wires from this connections (to reuse the plugs coming from the aircraft)
2. are they shrink wrapped and have to be cut off and start from scratch with new connectors from the aircraft AND from the new servo.

Never did this before so your expertise is much appreciated.

Just use a 9volt battery to test which white power wire drives the servo in which direction and label that wire accordingly.

Personally I'd ditch those connectors and replace the whole shoot'n match with a 9-pin Dsub connector.

Those are regular Faston terminals - Stein sells them as do thousands of other sources.

A DB9 would work here, or a Molex, or just about any other connector. If you use Faston terminals again, mark the wires with a Sharpie or something once you get them hooked back up and verify that the trim moves in the right direction.

Just mark wires 1 to 1 2 to 2 3 to 3 ect and check after repair.

There is a nice tidy upgrade available from Vans that replaces all those connectors with a single plug. It's on 'the list' about a dozen items from the top. '12 trim wire upgrade' is I think it is listed as. $7.00. Use a drill battery or similar to figure out which of the white wires is up and which is down.
There was a fairly recent discussion on the forum about the direction the anti servo (trim) tab should be moving. Use the search function to find it. Use the keyword 'trim tab' and you should finish up with more information than you need!
Hope this helps

white wires are the motor, reverse polarity for opposite direction, orange is power, green signal, blue ground, if using the Dynon for indication, the power is a 5 V feed from the Dynon EMS

I tried to find a picture of that but I was unsuccessful. Can anyone post one?

I agree with using DB-9 connectors. Wire it up and test the trim direction. If it is backwards from what you need, then just pull both white wires from one connector and reverse them. Once you have the correct direction, label the white wires 1 and 2 on both sides of the DB9 and you will never have this problem again.

There is a SteinAir video showing how they suggest this connection.

Here is how I did the trim servo wires on my 10.
