To get timing- You can plug a TV into the pitwall sockets using co-ax, but need to have a kit of male / female adaptors in case! Power by usual conti 2 pin. Haven't used it this year but used to be a bit 'well used' and 'flaky'...... Maybe they've improved it now.
Good news for any in endurance pit lane is that it was all re surfaced during the winter! Definitely need a wheel chock now......
Oh, and at night only entrance you can re-enter by is STER gate. Last month, even though Blanchimont was manned at 10pm and we had all the correct passes, we were refused entry and had to drive round to Ster.
