GTN 625 pins

Just about done with the GTN 625 connector. I noticed that not all cables needed for an ELT-GPS connection exist in the harness so I ran a 2x20 shielded cable all the way from the panel to the tail.

Reminder for myself: RS232-1
Shield is 232-gnd

My first crimped koax connector (for the GTN625 GPS Antenna)

Lots of wires, main power in place

First I realized that I had totally forgotten to wire the left traditional magnet. I fixed that and supported some emag cables better.

I have finally gotten my 80amp ANL fuses so I ended with wiring up the main power distribution. (Alternator, ANL, shunt, Bat-main fuse block-MGL ECB) Hopefully this is as messy as it will ever get and that it will look better and better from now on.

FW forward wires

Lots of things done in the last two days but not much to show in pictures. Basically all the wiring on the front side of the FW is done now. All wires are either grounded on the engine side or going thru the two openings in the FW.

Front plate for fuse holder

I need a bigger/better CNC mill! I cannot trust the CNC to keep its position so milled slowly using a G-code command at a time.

Cables & Switches

Work from today and yesterday. Added switches to the panel mid section and made a cutout for the planned ICOM 220. Then I started installing the control cables.

Master switch

I connected the Master Switch and placed a small 12v battery on top of the "real" battery and connected it after verifying that no power cables touched anything. I then tested the Master Switch and got the typical "chunk" sound from the engaging Master Relay.

Problem with comments

I have continued with more CAN BUS wiring, not much to show. I do not want to pull more wires thru the firewall before I have put the engine control cables thru the same holes.


For some reason I am not able to respond to the comment in the last post... twice I have responded and the posts just disappears. So my reply below:


Damaged goods are unfortunately very common nowadays. Totally lost goods also happens. I have been lucky, I think this is the first time ever that I have had a shipment lost or significantly damaged.

Shit happens...

My shipment from Vans with among other things my custom control cables was lost/destroyed during shipment.


Shit happens as they say, I must say that both FedEx and Van´s have handled the incident perfectly and to be honest I have and will not loose much time because of this. I have had lots of tasks to perform that was not depending of this shipment, I just have been prioritizing family and non aviation related things for the last 5-6 weeks.


Last night I spliced cables from the pressure senders, no pics from that, sorry. I am also almost done with the primary electrical system so a first start up of the EFIS and GPS in the panel should not be far away.
