Where can I find schematic diagrams or cross-references for pin-outs on relays?

[datsa]

I'm working on several electrical mods for my car and was planning on using genuine Toyota relays (mostly because I've got dozen spares pulled from junk yards). Although I have the Toyota electrical wiring diagram, they don't have great details on the relays, and none of the relays has their pins identified, so I can't tell which is pin 1, pin 2, etc that the electrical diagram refers to. Of course, I can just trace the color of wires into the matching relay on my Corolla and use that, I suppose.

I guess I should either try that or contact Denso. Googling hasn't helped so far.

what do they pins on the relay look like? (what pattern are they in)

All are in patterns of either 4 or 5 which I assume refers to single pole single throw (SPST) or single pole double throw (SPDT) types, respectively. A reference website, http://the12volt.com has helped somewhat in this manner but they like to use Bosch relays. If I had a cross-reference to Denso relays, it would be great, but I haven't found it. I haven't gotten much help from Denso, even though they have a regional sales office in my home town. In the meantime, I am trying to trace wires and compare their colors to that in the electrical wiring manual for my car so I can tell which pin is which on the relay.

But I did just find these on the web:

you have to be careful with that center pin (on 5 pin relays). most of the time it is an 87a which works the opposite way the normal 87 does (it's on when the 87 is off). But I'm using a relay that has double 87s. (it powers a lot of stuff...)

is the relay labeled with those numbers? they're pretty standard as far as relays go.
