Megasquirt relay board

[merc-blue]

Ok so i have built and tested my MSII and it all looks good.
I will not be wiring it in until the new engine is built, and seeing i still dont have a block or crank im happy with it may be some time.

I am pretty comforable with wiring i compleated most of elec. eng. at tafe before changing into mech eng.

But im tempted to run a slightly moddified relay board (with another 25pin connector not screw terminals)

I would like to see a compleated one and also opinions on how much tidyer it made the install, i plan to compleatly seperate the boody and engine loom with a small plugged section to connect the two, toyota arent really good with modulated looms.

Im all for tidyness of the install while keeping functionality

i've found the relay board to be a bit of a pain - is one more DB37 to solder up and potentially fail (in my case, the FP trace disconnected just outside armidale).

I have a sub loom from engine to relay board which is handy but i use screw terminals.

my preference would be to get a decent firewall connector (e.g. a round milspec thing) so you have an engine loom and separate loom from firewall to ECU. You'd also have to device whether to include dash sensors and Alt wiring in this.

If you do make a modified relay board, i'd suggest some tell-tale lights on some important outputs (Inject power, FP power, Idle-up power), power and earth and signal connections for O2 heater (if you run narrowband), or similar connections for wideband (if used) - otherwise you have some devices connecting at the ECU and others in the engine bay, making a mockery of the whole point of the relay board
