Not sure whether it's just my browser but that file is not ledgible John and the mag button just blurs it more?

ooops - I should have checked the PDF closer.

Cheers John, been pouring over the file for an hour or so and there sees to be a few differances to how mine is wired
1.I have the main relay pin 87 spliced to pin 85 on the fuel pump relay which in turn runs to 02 heater relay(diagram main relay 2) but it seems spliced to pin 86 in your diagram not sure where it runs to blue square with an a in it?
pin 86 on mine runs to e1 grn/yel
2.Pin 86 on my main relay runs to e7 red/yel but again on your diagram seems that pin 85 runs to e7 red/yel
This is based on the fact that it matters as I don't know a great deal about relays other than they are a switch
3.can't see 02 relay anywhere?
4. Totally fu**ing confused now...........

Craig - on my type-r donor, there was no relay for the O2 sensors, all wires went directly to the ecu.
On standalone ECUs I've installed in other cars as a matter of routine I've installed relays for the lambda heaters, as I didn't fancy flowing teh current through the ECU. I was toying with doing the same with the Honda ECU just to be sure I didn't zap it.
I believe the JDM / US cars have relays, as they work with the wideband lambdas, which have different power requirements. I might be wrong though.
The 2 PGM-F1 relays on my donor were wired in exactly as shown on the wiring diagram document posted above.
There's a constant fused 12v feed to pin 30 on relay 1, an IGN-1 feed to pin 85, 86 goes to the ECU (which switches to ground when the ecu see an IGN1 feed on E9). Pin 87 goes to pin 30 on the second relay (fuel pump). The other pins on the second relay are as follows: pin 87 to the +ve side of the fuel pump, 85 is linked to pin 30, and pin 86 goes to the ecu, which again grounds when activating the fuel pump (2 seconds when first turning the ignition on, and then continuusly when seeing a crank signal).
It's certainly quite a brain teaser sorting it all out! Check out the laughably messing current state of my wiring.

That picture is certainly interesting I would not know where to start! I'm going for the bare minimum with wiring, I think that I am going to spend the day trying to get my ignition sorted so that I have power at least
I did my engine mount last night (gearbox) after an hour or so it was sorted and looks at lot more upto the job.....but I had made a crucial mistake one that I would not normally make if I weighed things up properly but it was late and I wanted to see it finished.
I had not taken into account when welding the new mount in place the flexability of the new one so when I dropped the weight of the engine back down (yes you have probably guessed it the engine sloped slightly)
My own fault so off it came re-welded and back on looking good
